I was playing around this morning with steepened twills for my Exploring Multishaft Design study group and discovered this interesting little puzzle: given a twill, you can steepen the twill line or make it shallower by skipping shafts in the threading or the treadling. This isn’t new news, but I then discovered that if you skip shafts in both the threading *and* the treadling, you get a “normal” twill back, but it does not resemble the original twill! (See file and photo below.)
The question I posed to my study group is, what relationship does the new twill have to the original one? This seems mathematically interesting to me…
If we come up with an answer, I’ll post that too.
Weaving is such fun!
