...Maybe....? Surely I would have noticed throwing two because they un-weave on my Ashford table loom if I do that. Its only visible on one side, so I wonder if I had a sticky shaft? When it rains that 4th shaft sticks. I think I'll try to rub some wax on the frame before I start my Parrot Fibonacci w/Gradation. I find that the loom moves across my table quite a bit when I beat, so maybe I pull it out of square and that's causing the shafts not to fall?
I guess I'll see if putting it on an old yoga mat on top of the table and maybe clamping it down to my table helps.
Who knows... I WISH I could afford a floor loom. I have a 32", 8 shaft, Ashford table loom right now, without the stand or treadles.
