It's funny you brought that up, because I just began having that problem this week. I was doing the same thing, standing on something so I could let the yarn/project dangle and spin until it was untwisted. I've never had it happen before now, though. I assumed it must've been the yarn I was using, but then it also began happening with another yarn, which I have used before. :?? It is very annoying! :?eyebrow:
I forgot to mention that I was keeping my ball of yarn in a zip loc bag at the time, too.
