This post is the third in a series introducing you to common weaving structures. We’ve already looked at plain weave and twill, and this time we’re going to dive into the magic of overshot weaves—a structure that’s very fun to make and creates exciting graphic patterns.

Overshot is a term commonly used to refer to a twill-based type of weaving structure. Perhaps more correctly termed "floatwork" (more on that later), these textiles have a distinctive construction made up of both a plain weave and pattern layer. Requiring two shuttles and at least four shafts, overshot textiles are built using two passes: one weaves a tabby layer and the other weaves a pattern layer, which overshoots or floats, above.

Readers in the United States and Canada may be familiar with overshot textiles through woven coverlets made by early Scottish and English settlers. Using this relatively simple technique, a local professional weaver with a four-shaft loom could easily make a near-infinite variety of equally beautiful and complex patterns. If you’d like to learn more about overshot coverlets and some of the traditions that settlers brought with them, please see my reading list at the bottom of this article!

As it is twill-based, overshot will be very familiar to 4 shaft weavers. It’s made up of a sequence of 2-thread repeats: 1-2, 2-3, 3-4, and 1-4. These sequences can be repeated any number of times to elongate and create lines, curves, and shapes. These 2-thread repeats are often referred to as blocks or threading repeats, IE: 1-2 = block 1/A, 2-3 = block 2/B.

There are three ways weft appears on the face of an overshot cloth: as a solid, half-tone, or blank. In the draft image I’ve shared here, you can see an example of each—the solid is in circled in blue, the half-tone in red, and the blank yellow. Pressing down the first treadle (shafts 1 and 2), for example, creates solid tones everywhere there are threads on shafts 1 and 2, half-tones where there is a 1 or 2 paired with 3 or 4, and nothing on the opposite block, shafts 3 and 4. Of course, there’s not really nothing—the thread is simply traveling on the back of the cloth, creating a reverse of what’s on the face.

Because overshot sequences are always made up of alternating shafts, plain weave can be woven by tying two treadles to lift or lower shafts 1-3 and 2-4. When I weave two-shuttle weaves like overshot, I generally put my tabby treadles to the right and treadle my pattern picks with my left foot and my tabby with my right. In the draft image I’ve shared above, I’ve omitted the tabby picks to make the overarching pattern clearer and easier to read. Below is a draft image that includes the tabby picks to show the structure of the fabric.

Traditional overshot coverlets used cotton or linen for warp and plain weave wefts, and wool pattern wefts—but there’s no rule saying you have to stick to that! In the two overshot patterns I’ve written for Gist, I used both Mallo and Beam as my pattern wefts.

In the Tidal Towels, a very simple overshot threading creates an undulating wave motif across the project. It’s easy and repetitive to thread, and since the overshot section is relatively short, it’s an easy way to get a feel for the technique.

The Bloom Table Squares are designed to introduce you to a slightly more complex threading—but in a short, easy-to-read motif. When I was a new weaver, one of the most challenging things was reading and keeping track of overshot threading and treadling—but I’ve tried to make it easy to practice through this narrow and quick project.

Overshot works best with a pattern weft that 2-4 times larger than your plain weave ground, but I haven’t always followed that rule, and I encourage you to sample and test your own wefts to see how they look! In the samples I wove for this article, I used 8/2 Un-Mercerized Cotton weaving yarn in Beige for my plain weave, and Duet in Rust, Mallo in Brick, and Beam in Blush for my pattern wefts.

The Bloom Table Squares are an excellent example of what weavers usually mean when they talk about traditional overshot or colonial overshot, but I prefer to use the term "floatwork" when talking about overshot. I learned this from the fantastic weaver and textile historian Deborah Livingston-Lowe of Upper Canada Weaving. Having researched the technique thoroughly for her MA thesis, Deborah found that the term "overshot" originated sometime in the 1930s and that historical records variably called these weaves "single coverlets’ or ‘shotover designs.’ Deborah settled on the term "floatwork" to speak about these textiles since it provides a more accurate description of what’s happening in the cloth, and it’s one that I’ve since adopted.

Overshot is a magical structure. The first time you weave it you can hardly believe the cloth that grows on your loom. Traditionally used to weave bed coverings, overshot has many beautiful applications in today"s world, from useful household textiles to breathtaking works of art. This versatile weave is subject to endless variations. Here are a few of our favorite tips and a few truly spectacular projects, too! If you are inspired, come visit us and learn from a master weaver, Joanne Hall. See details below about her workshop.

A slouchy bag by FiberMusings on Weavolution pairs leftover BFL singles with sturdy Cottolin to create a fashionable yet functional multi-colored bag. The draft is a design from Ann Weaver"s Handweavers Pattern Dictionary, and it"s a great way to integrate Overshot techniques while making an eye-catching accessory!

Another project that caught our eye recently was a shower curtain shared by GailR@30 shared on Weaving Today - it"s nothing short of amazing (click here to see for yourself)! Consisting of thirteen different overshot pattern threadings woven in thirteen different treadlings, 169 different design effects are created based on designs from Osma Gallinger Tod"s book The Joy of Handweaving. As Gail noted on her project page, a great way to make each design stand out is to separate them with twill bands (even though it might mean a little more work in the process!)

Or, you may choose to elevate your weaving like the work of art it most certainly is, as Evaweave did with her Overshot Study pieces. These two miniature silk rugs look lovely in a frame, don"t you think? The overshot pattern was adapted from Overshot Weaving by Ellen Lewis Saltzman, complementing one another perfectly.

Think overshot is too difficult to try? Deb Essen thinks otherwise! Fiber artist, designer, and teacher, Deb is a passionate weaver who specializes in using overshot name drafts to create "secret messages" in cloth.

On her website, she explains: "Overshot is a weave structure and a draft is the weaver"s guide to creating patterns in cloth. Overshot name drafts assign the letters of a name or phrase to the shafts on a loom, creating a pattern that is unique. The one-of-a-kind patterns become a secret hidden message in the cloth and only those knowing the secret can break the code."

Deb lets you in on the secret with her clever kits, each with a hidden message. We"re particularly fond of her That"s Doable kit, which features Mountain Colors hand-painted yarns and, as the name would imply, is our first choice for those new to overshot weaving.

I have taken the time to record some of the larger coverlet radiating overshot pattern drafts in profile draft form making them more accessible to weavers who use drafting software. From the profile you can try different structures, colors and layouts to find a design that is pleasing to you. I have built instructions that show you how the draft is composed and how it can be modified. I would like to think of it as giving you design components more than a formal project plan. If you want the formal project plan approach use the Woven as Drawn in instructions. My goal in my presentation is to increase your understanding so that you can design your own projects and not not to restrict you to copying standardized patterns.

I added an eBook/PDF and draft package for Radiating Overshot Patterns  – Sunrise, Blooming Leaf, Bow Knot and the Double Bow Knot. These designs include full drafts, profile drafts and woven as drawn-in drafts. This is the link to purchase the draft archive and the instruction ebook: https://historicweaving.com/wordpress/product/radiating-patterns-for-historic-overshot/

The origin of the technique itself may have started in Persia and spread to other parts of the world, according to the author, Hans E. Wulff, of The Traditional Crafts of Persia. However, it is all relatively obscured by history. In The Key to Weavingby Mary E. Black, she mentioned that one weaver, who was unable to find a legitimate definition of the technique thought that the name “overshot” was a derivative of the idea that “the last thread of one pattern block overshoots the first thread of the next pattern block.” I personally think it is because the pattern weft overshoots the ground warp and weft webbing.

Overshot gained popularity and a place in history during the turn of the 19th century in North America for coverlets. Coverlets are woven bedcovers, often placed as the topmost covering on the bed. A quote that I feel strengthens the craftsmanship and labor that goes into weaving an overshot coverlet is from The National Museum of the American Coverlet:

Though, popular in many states during the early to mid 19th centuries, the extensive development of overshot weaving as a form of design and expression was fostered in rural southern Appalachia. It remained a staple of hand-weavers in the region until the early 20th century. In New England, around 1875, the invention of the Jacquard loom, the success of chemical dyes and the evolution of creating milled yarns, changed the look of coverlets entirely. The designs woven in New England textile mills were predominantly pictorial and curvilinear. So, while the weavers of New England set down their shuttles in favor of complex imagery in their textiles, the weavers of Southern Appalachia continued to weave for at least another hundred years using single strand, hand spun, irregular wool yarn that was dyed with vegetable matter, by choice.

And, due to the nature of design, overshot can be woven on simpler four harness looms. This was a means for many weavers to explore this technique who may not have the financial means to a more complicated loom. With this type of patterning a blanket could be woven in narrower strips and then hand sewn together to cover larger beds. This allowed weavers to create complex patterns that spanned the entirety of the bed.

What makes overshot so incredibly interesting that it was fundamentally a development of American weavers looking to express themselves. Many of the traditional patterns have mysterious names such as “Maltese Cross”, “Liley of the West”, “Blooming Leaf of Mexico” and “Lee’s Surrender”. Although the names are curious, the patterns that were developed from the variations of four simple blocks are incredibly intricate and luxurious.

This is only the tip of the iceberg with regard to the history of this woven structure. If you are interested in learning more about the culture and meaning of overshot, check out these resources!

The National Museum of the American Coverlet- a museum located in Bedford, Pennsylvania that has an extensive collection of traditional and jacquard overshot coverlets. Great information online and they have a “Coverlet College” which is a weekend series of lectures to learn everything about the American coverlet. Check out their website - coverletmuseum.org

Textile Art of Southern Appalachia: The Quiet Work of Women – This was an exhibit that traveled from Lowell, Massachusetts, Morehead, Kentucky, Knoxville, Tennessee, Raleigh, North Carolina, and ended at the Royal Museum in Edinburgh, Scotland. The exhibit contained a large number of overshot coverlets and the personal histories of those who wove them. I learned of this exhibit through an article written by Kathryn Liebowitz for the 2001, June/July edition of the magazine “Art New England”. The book that accompanied the exhibit, written by Kathleen Curtis Wilson, contains some of the rich history of these weavers and the cloth they created. I have not personally read the book, but it is now on the top of my wish list, so when I do, you will be the first to know about it! The book is called Textile Art of Southern Appalachia: The Quiet Work of Women and I look forward to reading it.

In this article, I focus on designing with overshot blocks in order to create flowing curves large enough to be seen at a distance. I will also discuss "weaving as overshot" which is a method of applying overshot techniques to other weave structures and, finally, finish up with some strategies for designing curves in any weave structure.

In the twill draft above, the diagonal lines are only three threads apart, which might be too subtle an effect. To make the scale of your design larger, you can use a diagonal progression of weave-structure blocks instead of individual threads. The following draft shows an example of a diagonal progression using overshot blocks on four shafts.

Overshot is a weave structure creating a plain-weave cloth with decorative supplementary weft floats. These floats lie on top of (float over) the ground cloth. If you pull out all of the pattern weft threads, you are left with a plain weave cloth formed by the warp and the tabby weft. There are never any warp floats because of the tabby weft.

Weaving software is very helpful for testing hues and values for weft yarns to use with your warp. If you choose to weave overshot with a single shuttle, choose a contrasting value to the warp for a subtle design but faster weaving.

If you put the curve in your threading, the waves travel across the fabric horizontally, in the direction of the weft. You can see this in the overshot draft below.

I learned how to make curves by studying a traditional overshot draft called Blooming Leaf (page 133 in A Handweaver"s Pattern Book by Marguerite Davison). In this draft, the treadling maintains a diagonal progression but the scale changes to make the shape "bloom" and undulate.

[Note: When I create overshot drafts, I place the first pattern block on treadle three; I like to weave the tabby picks with my left foot (alternating between treadles one and two) and use my right foot (on the remaining treadles) to weave the pattern weft and create the design.]

Now that you know how to create curves, undulations, and reflected curves, you have the tools you need to create any kind of curve or diagonal line in four-shaft overshot. For a challenge, try making a long curve followed by a short curve, like a meandering river.

The methods described above also work for overshot on six, eight, ten, or more shafts. As you add additional shafts to your design, you gain the ability to create smoother and more dramatic curves.

Below is an example of an eight-shaft overshot threading; in this case a diagonal progression with a point and mirror symmetry. My treadling in this draft is an S-shaped curve. This is just one example of the many different curves you can weave on this threading.

Because the underlying structure of overshot is plain weave, any threading which can produce plain weave can theoretically be woven as overshot, alternating tabby and pattern weft.

I wove the draft above using a 20/2 silk sett at 30 epi. I chose to sett the yarn this densely so I could weave both an overshot and twill version on the same warp. You can see the resulting cloth in the picture below.

How do I weave as overshot when my sett is more appropriate for twill? I use a tabby weft that is much finer than the warp, in this case 140/2 silk from Lunatic Fringe.

Other times I choose to weave as overshot because the floats show off the pattern-weft yarn, such as the handspun wool used as the pattern weft in the cloth below.

It is easy and fun to make up a curved treadling at the loom, especially when weaving as overshot. Even after forty-two years of weaving, I still enjoy working with long, non-repeating treadlings; watching the curves grow and change as I weave. Instead of memorizing a sequence and repeating it carefully, I watch the design and think about where I want the next curve to go.

The drape of overshot fabric is not as fluid as that of a twill fabric. So for a scarf or shawl I might choose a structure other than overshot. Fine silk, however, has such nice drape that I can weave as overshot and still get good results.

With weaving software, it is easy to create curved overshot designs. Simply draw a freehand curve in the treadling—smoothing it out if necessary—and then add the tabby shots. Once you have the general idea from designing drafts, you can improvise new curved designs at the loom.

For other weave structures, creating a profile draft can be helpful. A profile draft is a design template that represents the woven design at one level of abstraction. To convert a profile draft into a weaving draft, you replace each block in a profile draft with the appropriate block of a given weave structure. You can, therefore, express a single profile draft in many different weave structures: overshot, summer-and-winter, Bronson lace, huck lace, double weave, etc.

I like smooth, flowing curves that are visible at a distance. So I look for structures that give me the maximum number of pattern blocks to design with. Generally I use weave structures where I have as many pattern blocks as there are shafts on my loom. On a four-shaft loom, I use crackle, overshot, advancing and network-drafted twills, advancing points, turned taqueté, rep, and shadow weave.

In its simplest form – overshot is a weaving technique that utilizes at least 2 different types of weft yarns and floats to create a pattern. These patterns are often heavily geometric.

Ground weft– plain weave pattern that is used between each row of your overshot pattern. This plain weave gives the textile structure and allows for large areas of overshot to be woven without creating an overly sleazy fabric. Without the use of a ground weft on an overshot pattern, the weaving would not hold together because there would not be enough warp and weft intersections to create a solid weaving.

They were most popular though in southern Appalachia and continued to be so even after textile technologies advanced. When other parts of colonial America moved to jacquard weaving, the weavers of southern Appalachia continued to weave their overshot coverlets by hand.

Since the overshot coverlets were most often woven at home on smaller looms they usually had a seam down the middle where two woven panels were sewn together.

The thing about overshot is that no matter the application, it is pretty impressive. Perhaps that is just my opinion, but due to how complex it can look, I feel that it is pretty safe to say.

The discontinuous weft yarns will float onto the back of the weaving until you are ready for them in their next pick. This does make your overshot weaving one sided since it will have vertical floats on the back. Keep this in mind if you want to try this technique out.

Also seen in the image above, the overshot yarn that I used was not all one color! This is a really simple way to get extra dimension and interest in your overshot if that is something you are looking for.

This makes it simple to be able to only weave overshot in certain parts of your weaving. If you want to do this then you can continue to weave your plain weave across the entire width of your weaving, but only weave overshot in specific areas. This creates a overshot section that functions similar to inlay.

Since the overshot pattern is strongly influenced by the weft yarns that are used it is important to choose the right yarns. Your weaving will be set up to the specification needed for a balanced plain weave. Make sure you understand EPI in order to get the right warp sett for your overshot weaving.

The ground weft used is almost always the same yarn as your warp. This allows the overshot weft to really be able to shine without contrasting warp and weft plain weave yarns.

In order to get the full effect of the overshot, it must be thick enough that when you are weaving your pattern it covers up the ground weft between each pass. If it is not thick enough to do this, it will still be overshot, but the full effect will not be seen.

What this warp thread does is serve as an all-purpose selvedge that does not correspond with your pattern. Instead, you would make sure to go around this warp thread every time to make sure that you are able to weave fully to the selvedge. Without this, your overshot weft will float awkwardly on the back of your weaving whenever the pattern does not take it to the edge.

I have mentioned this book multiple times because it really is such a great resource for any weaver looking to weave patterns of all types. It contains 23 pages of different overshot patterns (among so many other patterns) that you can set up on your floor or table loom.

Weaving overshot on a frame loom or rigid heddle loom will require the use of string heddles and pick-up sticks that you have to manually use to create a shed.

Overshot is an intricate weave structure in which pattern weft “shoots over” a grounded plain weave cloth to create a huge range of patterns. From undulating waves to dashing circles, the weaver can create complex patterns on only 4 shafts. This weave structure has been used all over the world, but developed most widely in Appalachian coverlets and table linens during early colonial America. In this class, students will learn more about this beloved weave structure and weave their own overshot table runners, placemats, or samples using cotton and wool on 4 shaft floor looms. Explore blending colors, manipulating patterns, and practicing weaving this two shuttle weave structure. No weaving experience is necessary, but some experience is helpful.

Overshot is the most American and most Canadian of weave structures. I’m not saying that the U.S. and Canada are the only countries that can claim overshot or that they invented the structure. What I am saying is that weavers north and south took the overshot drafts brought over from Europe and made them their own.

To understand the reason for overshot’s popularity, you need to understand the weavers of pre-Industrial Revolution America and Canada. With the exception of those who worked on luxury, specialized fabrics, most weavers made household linens. The cloth needed to be strong and serviceable, and there was little room for experimentation or creativity—except, of course, for coverlets. Coverlets were functional items, but they also served the purpose of decoration. So, weavers of coverlets were free to play at the loom—and play they did.

The reason that weavers loved overshot then is much the same reason that many of us love it now—it’s a simple structure that produces complex patterning on just 4 shafts. With overshot, you can create circles, stars, flowers, and more. It’s also easy to take a draft and adjust it to create seemingly endless variations, which is exactly what happened during the 1700s and beyond. Household weavers would riff on drafts to create new designs, give them names, and then share the drafts with other weavers near and far.

As always, it’s been a busy couple of weeks. One of the members of my online weaving group on Our Unraveled indicated that she would like to make towels in the Lee’s Surrender overshot draft. Now Lee isn’t easy. It may be only a 4-shaft overshot draft, but it combines several elements, has a wicked border and isn’t for the faint of heart. Or at least isn’t for beginning weavers. The good news is that it is in Marguerite Porter Davison’s A Handweaver’s Pattern Book. The original book is from the 50’s and the draft is written out in the older format, but it still manageable. (Hint: beware of getting a new version of the book. I’ve heard that it has been gutted and has maybe half the drafts of the earlier editions.)

I don’t know where the original draft came from. In the book Davison says that it is adapted from an earlier pattern. Since weaving drafts, like quilt patterns, are frequently named for historical events, I assume this one is truly named for Lee’s Surrender of the Confederate troops at Appomattox Courthouse. If so, that would place it in the late 1800’s. The border is based on the Blooming Leaf pattern that appears in other overshot drafts, and this gives the border its intricate, eye-appealing size. The tables that form the center design are themselves quite simple – a star design commonly found in overshot. However, they allow the piece to be wider or narrower at the weaver’s discretion simply by adding or removing repeats.

I volunteered to make the draft for the requested towels and post it to the group. I also suggested that we use it as an overshot weave-a-long or WAL. Several people agreed and I think we’ll get going on the first of September. I was able to find the original notes and WIF (Weaving Information File) I entered when I made the place mats. I hadn’t finished the treadling diagram, but it wasn’t hard to finish up. I did all the calculations for two towels and wrote up the instructions. Unfortunately, I couldn’t test the towels prior to releasing the PDF. I’m hopeful that everything is fine and I didn’t make any mistakes. I suppose we’ll see.

An old pattern in overshot weaving that has had many names over time: Muscadine Hills, Hickory Leaf, Blooming Leaf. The Double Bow Knot name comes from the leaf like square that forms the larger portion of the design. The dark square is called a table. #weaving #overshot #coverlet #history

Overshot weave is the topic this week. Even if you haven’t heard of overshot before, I’m guessing you will still recognize it. Have you ever seen a historical coverlet before? That is overshot. Typically 2 colors. ALL about the pattern. That’s the one! Overshot.

Overshot is a partnership between 2 shuttles. The first shuttle is all about the pattern. She flits all over the fabric making big leaps and seemingly impossible designs. The second shuttle is all plain weave. She’s the reliable one, making sure the fabric will actually hold together.

Overshot Weave – Overshot is a weaving pattern that was very common in Southern Appalachia. I found a great article with some history about overshot from Comfort Cloth Weaving. Here’s the link.

The most commonly reported type of Ecological Footprint, it is defined as the area used to support a defined population’s consumption. The consumption Footprint (in gha) includes the area needed to produce the materials consumed and the area needed to absorb the carbon dioxide emissions. The consumption Footprint of a nation is calculated in the National Footprint and Biocapacity Accounts as a nation’s primary production Footprint plus the Footprint of imports minus the Footprint of exports, and is thus, strictly speaking, a Footprint of apparent consumption. The national average of per capita Consumption Footprint is equal to a country’s Consumption Footprint divided by its population.

In contrast to the consumption Footprint, a nation’s productive Footprint is the sum of the Footprints for all of the resources harvested and all of the waste generated within the defined geographical region. This includes all the area within a country necessary for supporting the actual harvest of primary products (cropland, pasture land, forestland and fishing grounds), the country’s built-up area (roads, factories, cities), and the area needed to absorb all fossil fuel carbon emissions generated within the country. In other words, the forest Footprint represents the area necessary to regenerate all the timber harvested (hence, depending on harvest rates, this area can be bigger or smaller than the forest area that exists within the country). Or, for example, if a country grows cotton for export, the ecological resources required are not included in that country’s consumption Footprint; rather, they are included in the consumption Footprint of the country that imports the t-shirts. However, these ecological resources are included in the exporting country’s primary production Footprint.

Natural capital can be defined as all of the raw materials and natural cycles on Earth. Footprint analysis considers one key component, life supporting natural capital, or ecological capital for short. This capital is defined as the stock of living ecological assets that yield goods and services on a continuous basis. Main functions include resource production (such as fish, timber or cereals), waste assimilation (such as CO2 absorption or sewage decomposition) and life support services (such as UV protection, biodiversity, water cleansing or climate stability).

In this work we describe the topology and dynamics of the transcriptional network of plasmid R388, the smallest BHR plasmid from Proteobacteria. The network consisted exclusively of transcriptional repressors. This preference for transcriptional repression is in contrast with the situation described for the regulatory networks of bacterial chromosomes. For example, in E.coli the number of transcriptional activators roughly equals the number of repressors [33]. However, other transcriptional networks from BHR plasmids, like plasmid RP4, were also found to depend solely on transcriptional repressors [11]. In plasmid R388, transcriptional repression was exerted mainly in the form of negative feedback loops. These feedback loops showed high gains (defined as the ratio between the expression levels of the open and the closed feedback loops). Although we are not aware of any systematic, quantitative study of a plasmid regulatory network, several independent studies have reported that the regulatory network of plasmid RP4 contains strong promoters that are kept tightly repressed by the plasmid regulators [14], [34], [35],[36],[37],[38]. Remarkably, plasmids R388 and RP4 show similar broad host ranges, but they are not phylogenetically related [3], [4], [39]. This indicates that both plasmids, which presumably suffer from analogous selective constrains, have independently evolved transcriptional networks with analogous topologies.
