I love getting comments from my Post readers. And I love learning new things. A comment from Jon gave this threading to catch the outside warp thread. With it you don’t have to think and you don’t need a floating selvedge. I might not use it if I thought I would weave other structures besides twills in a piece, but it beats a floating selvedge if you plan a big twill project. Try to figure out how it works just from the threading.
Here is the regular 4-shaft twill tie-up. Can you see how a thread is always caught on each edge with every weft shot? Notice the circles in the tie-up. That’s because it’s showing shafts lifted. Remember that bubbles rise.
Now add the treadling. Can you figure out what the edges will look like from this information?
Here is the complete draft. The edges make a sort of plain weave. Perhaps you could thread more threads for the edges and make a border. Maybe an idea to ponder and worth trying? This is how my mind works—I’d want to do a sample first to see how the two weaves work. Now I’m thinking again…you could thread the edges: 22, 44 and 11, 33 to get a real basket weave on the edges and I think that should surely work with the twill. When I want bands of both twill and plain weave in a cloth, I often use basket weave instead of real plain weave because they both draw in the same. (If you use plain weave bands, they will turn out to be wider than the twill areas.)
