The Methow Valley Spinners & Weavers Guild has a “challenge” project every year, usually a particular type of weave structure, and everyone who wants to participate comes up with a project and we all try to learn something new together. The deadline is the second meeting in April, and we each provide copies of our own project sheet to the group This includes the threading, tie-up and treadling diagrams with the “drawdown” that gives a visual picture of what the cloth should look like, and specifications of the threads/yarns used, the size before and after finishing, whatever we learned, etc.
This year’s challenge is Overshot, which is often associated with traditional American bedspreads and coverlets. The structure of the cloth is plain weave, provided by the warp and a similar sized or slightly smaller tabby (plain weave) weft, alternating with a usually somewhat larger and softer colored pattern weft that floats over the surface (thus the term, overshot). The warp and tabby weft are usually white or cream color, with a coordinating pattern color.
But of course, I have to be different, so I used black for the warp and tabby, and dove into my box of miscellaneous Shetland 2-ply for a variety of pattern colors. I have at least 50-60 colors in this box, left over from knitting Fair Isle type sweaters, or bought as sample colors for designing sweaters.
I also became engrossed in a wonderful, out of print book by Helene Bress – The Weaving Book: Patterns and Ideas. I picked this up about a year ago online, managing to find a copy that wasn’t too outrageously expensive. Let me tell you, it is worth it. I decided to try her ideas of graduating color and size changes of the pattern blocks, using a traditional pattern from Marguerite Porter Davison’s A Handweavers Pattern Book : “John Madison” p. 156 in the chapter on Large Overshot.
The warp is 8/4 cotton rug warp in black, tabby weft is a 75% wool, 25% mohair on a large cone with about 27 wraps per inch, so a little finer but in the same ballpark as the warp. The pattern weft, as I said, a variety of colors of Shetland 2-ply jumper weight from Jamieson’s and Jamieson & Smith mills in the Shetland Islands.
These will be large table mats to be used on a small rectangular coffee table in our living room. I will put up pictures when they are finished, but here they were underway on the loom:
Testing the pattern to be sure I had the threading right:

John Madison test, using treadling I from M.P. Davison
Mat number 1, treadling a twill sequence, but varying the number of pattern shots for each treadle in the sequence 8-5-3-2-2-3-5-8 then repeat (a Fibonacci series), and alternating colors from dark to light back to dark within that sequence. One sequence in golds, then another sequence in olive green/browns, then repeat. Varying the number of pattern shots for each treadle makes the overall pattern undulate.

Mat number 2, treadling as twill, using Treadling II for “John Madison” from Davison’s book, which goes from 1 to 12 and then 12 to 1 in increments of 1. Alternating colors from light to dark back to light within that sequence, using 10 shades of red (I used the same bright shade for the 3-2-1-1-2-3 part of the sequence). I started the mat with 6-5-4-3-2-1 and ended it with 1-2-3-4-5-6 to put the brighter colors at each end and the darkest colors and largest blocks in the center.

I still need to darn in ends, wash and press, and hem these, but should have pictures by the end of the week.
Off to Wenatchee today!
Katie, you are awesome! The mats are just incredible.
Diana is correct! I really love “John Madison” Mat 2.
