The dobby loom is now rethreaded to straight draw. It will never have another change in threading (she says grandly). There's just enough left on the current mixed, mainly dark warp (20/2 and 20/2 cottons at 36 epi) for a bit of sampling before I tie on the next (straight) warp.
So here's a try of the crackle draft I was working on a few days ago. This is a simulation of a threading that could be woven on 4 shafts, here adapted to the 40-shaft straight draw. Click to enlarge.
There is one pattern weft (orange 5/2 cotton) and two 20/2 ground wefts (black and yellow). All I can say is: it works. Would I want to weave a lot of this fabric on this loom? Probably not. The chief satisfaction in working out this draft is just the challenge of seeing if it could be done. That's my favorite weaving activity: working out the What Ifs.
