The warp for cotton placemats is on the loom at my weaving class and half the heddles are threaded for Rose Path Project 1 (sampler) in Marguerite Perter Davison's A Handweaver's Pattern Book. This is the first time I've threaded heddles for twill. The dots on the pattern draft are arranged like the graphics of old arcade games, which is amusing.
I should shortly have a small rented floor loom to work on at home as well. I have on hand a good quantity of linen yarn to use, and simply need to choose between projects: more hand towels or a light-weight jacket. There are more ways a jacket could go wrong. Planning would take more thought and there's a risk I could incorrectly calculate the sett if I use a twill pattern.
I have more need of a jacket than towels. I've had two identical store-bought linen jackets for over a decade and they are so well loved they have become quite shabby. One recently went missing.
