At some point during my childhood, my mom aquired a long, black, "witch-style" wig. Every year for Halloween (she may even do it this year), she would dress up and play the witch for her friends' children. It was all in good fun, but she had (has?) a magnificent cackle. Her performance was a little intense for the smallest kids. Many of them seem to have a slight fear of women with very long hair, even now.
Anyway, a few days ago I ripped out an abandoned knitting project and used the gorgeous Malabrigo yarn as a warp. The tension was pretty even, although I had a little more trouble with the edges than usual. When I took it off the loom, though, I flashed back to mom's wig.
The kinks didn't seem to tangle, and I have it on good authority that, when washed, all will be forgiven and the yarn ends will relax. It's superwash yarn, and I hope that helps.
I'll let you know how it goes.
