Like I said, I don't knit, but my mother does, and every once in a while she gets hold of some yarn that is just maddening and won't behave at all. When you make yarn, you discover how many ways things can go wrong. The thing that most dependably stabilizes a yarn is plying--putting several yarns together seems to cancel out a lot of problems.
Thanks for the info. I know how warm it is as I am currently sitting under a throw made of baby alpaca. It gets warm enough that I need to throw it off occasionally!
As I think about this yarn It occurs to me that it is so slick and soft that it is the stitches that are shifting, more than the wool that is stretching. Guess I'll just finish this sucker off and see what happens.
