Here's the about-which part: Remember the difficulties I hoped to avoid last week, when I cut off the linen warp right after starting to beam it up? Well after tying on the newly-wound cotton warp (i.e., tying each cotton end to a linen end), I had enormous difficulty beaming this warp up, much to my chagrin. I spent all day Friday working on getting 6 yards beamed on -- I had so much difficulty and so many tangled warp ends that I cut off the last yard! Other than the previously mentioned Silk Warp From Hell, I'd never had this much difficulty beaming up a warp before, and couldn't for the life of me figure out what the problem was.
So Saturday morning I called Yarn Barn in Kansas, from where I'd purchased the 20/2 cotton, and the good folks there gave me a lesson in warping. Being a self-taught weaver, I was clueless about this, but probably many of you are already doing this. I warp front to back and I've always taken out the lease sticks (inserted before sleying to maintain the cross in the warp ends) right after sleying the warp through the reed. And I've always combed the threads with my fingers to straighten them, as I beamed up. Wrong! YB suggested I leave in the lease sticks all the way through the warping process, until it's beamed up and right up to where I have dangling ends in front of the reed which I'll now tie onto the front apron rod. They also suggested to NOT comb the warp with my fingers, but to keep it in chains and merely giggle each chain to straighten out the ends. Makes sense to me! Why didn't I think of that before now!?
Another likely problem with the cotton warp was that although the ends were the same length when I sleyed them, undoubtedly they were slightly different lengths after I tied them onto the linen ends, because of the placement of the overhand knots, which over 600 ends was bound to be different in places. The varying length of the ends, dragging by each other as I beamed up, caused the traffic jams at the heddles that I experienced (and nearly pulled all my hair out over! -- and I've got a lot of hair!!).
So, lesson learned, I might even try that linen warp again in the future!
