My favorite weave structure happens to be turned twill (also known as block twill). I love this structure because there are an endless number of ways to vary the threading, tie-up and treadling, and the structure lends itself very easily to color changes in both threading and treadling. A veritable weaver’s wonderland!
Block A in the above draft is threaded on harnesses 1-4 and Block B is threaded on harnesses 5-8.
With this tie-up, when treadles 1-4 are weaving the following happens:
Now, for my magical scarf.
I wanted my scarf to have just 2 warp-wise stripes, so I changed the threading so I had only one Block A and one Block B, like this:
Finally I changed the tie-up to make the horizontal stripe disappear on the right side. In the above draft,
By changing the face of the right lower quadrant of the tie-up from warp-faced to weft-faced, Block A (harnesses 1-4) will weave the same way whether it is being woven with treadles 1-4 or with treadles 5-8. The stripe in Block A has disappeared!
Now I wanted to weave a second scarf with stripes on the other side.
Further modifications to the tie-up allowed me to weaves stripes on the variegated side of my warp (in Block A on harnesses 1-4) while keeping the solid green side of the warp consistently weft-faced.
For the first half of the scarf
These experiments with the tie-ups for turned twill have taught me a lot and opened up a world of possibilities for more experiments with shapes and colors. I have another color block experiment going on to the loom now. I will shared the results in the near future!
