A few days ago I came across a reference to an article about 3-shaft twills which led me down an interesting rabbit hole (click on the link, and then click on the link DOWNLOAD THIS PDF FILE). In it, mathematician Shelley Rasmussen discusses the 30 possible weaves of size 3x3 through 6x3 possible on 3 shafts. Although I am no mathematician, I gleaned enough from the article to make me wonder about applying these weaves to a draft in which the threading is based on a network of 3-end twill. By a serendipitous chance, my 8-shaft loom is threaded with such a networked twill, and I set to work. Here is the draft for weaving polkadots in networked 3-end twill on 8 shafts.
Here is one of Rasmussen's 30 weaves and its insertion into the liftplan of the previous draft (one repeat shown):
And here is the result, combining the two effects in one draft, to produce a highly textured (might I say crepey?) weave with a flatter, graphically patterned border. First the draft, then the actual cloth on the loom.
For the truly curious, in case you're wondering about the logic of weaving 3-end twills on an 8-shaft loom, this would be considered a "turtle" type pattern line. More about turtles and network drafting in Network Drafting: An Introduction (see sidebar).
