Overshots are a tool used on the downhole process during the fishing operations. It engages the tube or tool on the outside surface. A Grapple or other piece of equipment that is similar attaches onto the overshot and grabs the fish.

A downhole tool used in fishing operations to engage on the outside surface of a tube or tool. A grapple, or similar slip mechanism, on the overshot grips the fish, allowing application of tensile force and jarring action. If the fish cannot be removed, a release system within the overshot allows the overshot to be disengaged and retrieved.

One interesting piece of information I learned is that overshot is a fairly modern term. Originally this type of weaving would have been referred to as floats or floatwork. It seems that many people are returning to this original terminology, though the weaving world has thus far shown little interest in making the change back. Personally, I like it. Floatwork sounds a bit less frenetic than overshot – as though I’m peacefully hitting my mark rather than missing it in a wild fashion.

Floatwork, formerly known as overshot which was originally known as floatwork, is a block design traditionally woven on four shafts where a heavier pattern yarn floats above a plain weave ground cloth and creates a raised pattern. Your plain weave background cloth is woven using a finer yarn in your warp and in every other weft pick (these weft picks being the ‘use tabby’ part of your pattern.)

This finer yarn is hidden in places by the thicker yarn floats, blended in places with the thicker yarn (as plain weave) creating areas that are shaded (referred to as halftone), and woven across itself to create delicate areas of plain weave. Most of us think of antique coverlets when we hear ‘overshot.’

Here is the thing about floatwork that really helped it to make sense for me. It is basically a twill weave. As Mary Black puts it, “An examination of an overshot draft shows it to be made up of a repetitive sequence of the 1 and 2, 2 and 3, 3 and 4, and 4 and 1 twill blocks”.

You can find it listed in the chapter or sub-chapter entitled ‘Notes on the Overshot Drafts.’ As someone who generally cheers on the underdog, I was drawn to this pattern without a name.

Here is a list of books and magazines that might be of interest if you’d like to learn more about floatwork/overshot. Many of these references include patterns in addition to thorough instructions.
