I'm hoping to weave a baby blanket using 3/2 perle cotton but can not achieve an even tension when tying on my warp. Warp is 40" wide, 90 " long set at 15 epi on an 8 shaft Macomber. After warping from the back, threading and slaying, I tied the ends in groups of eight. But the knots are not holding evenly and I end up with a very uneven tension. The third attempt was tied very tight, than mop was woven to the point where I could get the warp over the front bar. I was hoping this would help but it did not. Still too many ends lossened up and I'm getting many skips while trying to weave a tabby. This is my first time using 3/2. In the past I have used 5/2 and 8/2 without any issues. Has anyone else experienced this? Any ideas on what the problem may be?
