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.

As with all DeviGyro based survey solutions, quick, comprehensive, high precision, continuous surveying is made possible with the DeviGyro Overshot Xpress (OX). With the added ability to retrieve the core tube during the survey, the OX truly enables surveying to become a part of the drilling cycle and therefore increasing overall drilling productivity.

Step 1, at period start, the category lead defines the savings he or she believes are achievable in their area of responsibility. This is set as their performance target, and a share of these savings (percentage a) is used to define their incentive. For simplicity here, we will define this as the base bonus that will be the starting point of the lead"s bonus calculation at the end of the period.2 2.We want to stress that an incentive system does not need to be connected to a direct financial payment; we are using money as an example here only for the sake of simplicity.

Spend volumes and the ease of achieving savings will differ from category to category. Therefore, companies may not wish to link the bonus directly to the cash savings number achieved by each category lead. A pragmatic alternative is to define an absolute bonus number for good performance in line with the category lead"s tenure and additional salary components (e.g., in line with the previous year"s bonus payment) and divide this by an estimate of the savings available in the category to give the base bonus share (percentage a). This initial estimate will inevitably be a top management approximation and it must be made with some care: for categories that recently have been tackled, savings estimates will be need to lower than those for untouched categories, for example. The exact percentage can be adapted in direct negotiations with the responsible category leads. Critically, whatever the agreed percentage in their category, the formula still motivates the lead to provide as accurate a savings forecast as they can in order to maximize their final bonus.

The sandbag-busting effects of the proposed incentive model can be illustrated with a fictitious example. Let"s consider the bonus for a category lead in Travel named "Paula," who supervises a total spend of €50 million. Paula’s management asks her for her savings estimate for the upcoming period. Let us further assume she believes that a savings of €2.5 million (5 percent) is realistic. Under the model we propose, her bonus is linked to the target (savings estimate) at three points.The base bonus (percentage a) is defined as a proportion of Paula’s savings estimate: a=1%

Overshot: The earliest coverlets were woven using an overshot weave. There is a ground cloth of plain weave linen or cotton with a supplementary pattern weft, usually of dyed wool, added to create a geometric pattern based on simple combinations of blocks. The weaver creates the pattern by raising and lowering the pattern weft with treadles to create vibrant, reversible geometric patterns. Overshot coverlets could be woven domestically by men or women on simple four-shaft looms, and the craft persists to this day.

Summer-and-Winter: This structure is a type of overshot with strict rules about supplementary pattern weft float distances. The weft yarns float over no more than two warp yarns. This creates a denser fabric with a tighter weave. Summer-and-Winter is so named because one side of the coverlet features more wool than the other, thus giving the coverlet a summer side and a winter side. This structure may be an American invention. Its origins are somewhat mysterious, but it seems to have evolved out of a British weaving tradition.

Multi-harness/Star and Diamond: This group of coverlets is characterized not by the structure but by the intricacy of patterning. Usually executed in overshot, Beiderwand, or geometric double cloth, these coverlets were made almost all made in Eastern Pennsylvania by professional weavers on looms with between twelve and twenty-six shafts.

America’s earliest coverlets were woven in New England, usually in overshot patterns and by women working collectively to produce textiles for their own homes and for sale locally. Laurel Thatcher Ulrich’s book, Age of Homespun examines this pre-Revolutionary economy in which women shared labor, raw materials, and textile equipment to supplement family incomes. As the nineteenth century approached and textile mills emerged first in New England, new groups of European immigrant weavers would arrive in New England before moving westward to cheaper available land and spread industrialization to America’s rural interior.

Southern coverlets almost always tended to be woven in overshot patterns. Traditional hand-weaving also survived longest in the South. Southern Appalachian women were still weaving overshot coverlets at the turn of the twentieth century. These women and their coverlets helped in inspire a wave of Settlement Schools and mail-order cottage industries throughout the Southern Appalachian region, inspiring and contributing to Colonial Revival design and the Handicraft Revival. Before the Civil War, enslaved labor was often used in the production of Southern coverlets, both to grow and process the raw materials, and to transform those materials into a finished product.

A disruptive innovation, by definition, starts from one of those two footholds. But Uber did not originate in either one. It is difficult to claim that the company found a low-end opportunity: That would have meant taxi service providers had overshot the needs of a material number of customers by making cabs too plentiful, too easy to use, and too clean. Neither did Uber primarily target nonconsumers—people who found the existing alternatives so expensive or inconvenient that they took public transit or drove themselves instead: Uber was launched in San Francisco (a well-served taxi market), and Uber’s customers were generally people already in the habit of hiring rides.

First, researchers realized that a company’s propensity for strategic change is profoundly affected by the interests of customers who provide the resources the firm needs to survive. In other words, incumbents (sensibly) listen to their existing customers and concentrate on sustaining innovations as a result. Researchers then arrived at a second insight: Incumbents’ focus on their existing customers becomes institutionalized in internal processes that make it difficult for even senior managers to shift investment to disruptive innovations. For example, interviews with managers of established companies in the disk drive industry revealed that resource allocation processes prioritized sustaining innovations (which had high margins and targeted large markets with well-known customers) while inadvertently starving disruptive innovations (meant for smaller markets with poorly defined customers).

In simple terms, overshoot is a temperature rise that exceeds the set-point defined by the temperature controller. This is generally caused by thermal oscillations characteristic of on/off control actions.

A basic temperature controller uses a simple on/off control to generate and maintain process temperatures through electrical heating. When switched on, the heater load continuously converts a voltage into heat which is monitored by an integrated thermocouple. This thermocouple feeds back the process temperature to the controller, which monitors actual process conditions against the user-defined setpoint. If the temperature rises above the setpoint, the voltage is switched off and the temperature subsequently drops. This process is conducted rapidly and synchronously, generally forming a tight waveform that oscillates around the user setpoint within an instrument-specific percentage of the controller’s full temperature scale.
