I'm weaving a variation of Granny Pam's towels just for a little boucle fun. When I spread the warp, I noticed the fell line on the left was a little high, so I untied the knot and tied it a little tighter; that bout of threads felt a little looser than the others. It seemed to work so I started weaving. Everything looked good until it didn't. As I was nearing the end of the first towel, I noticed that the left end of fell line was a quarter inch higher than the right end. It was a gradual increase from just about the center of the 22 2/3 inch towel. I thought that maybe it had to do with tucking a tail when I changed colors so I un-wove about 6 inches. At that point I measured again and it was about 1/8 of an inch higher on the left than the right. Progress, but not a solution.
Is a little variation just part of working with boucle?
Is there a solution other than cutting off the current weaving and tying on again? In retrospect, I wonder if untying that first bout of threads and retying it after I'd already woven a couple inches of spreading threads at the beginning was the problem?
I'm weaving on a 4-shaft Baby Wolf (26 inch, I think). I never have this problem on the right side, only the left. I warp right-to-left. There are more empty heddles on the left side than the right side, would that matter?
Any help is greatly appreciated.
