Anyway, I took it off the chair back and it totally curled in onto itself! I was totally devastated... I didn't think that the spinning had gone badly, and I had no idea what went wrong. The websites and youtube videos weren't that helpful to me at this point. But anyway, somewhere I read to wet the wool and hang it with a weight suspended from it, so that is where I am now. Hopefully it will straighten out the overtwisting. I will try plying next time and maybe that will help.
