Nostepinne
I've been checking out ball winders for some time now, and while they aren't insanely expensive (not all of them anyway) I haven't been able to settle on a model. I don't remember exactly where, but I read somewhere about a nostepinne (nostepinde) and that it was used for ball winding. This is possibly common knowledge to seasoned knitters, but I'm self-taught & still relatively wet behind the ears -- what's a nostepinne?! Thus I started snooping around online to find out what this thing was. It's basically a little wooden baton that you wrap yarn around -- nothing more, nothing less.
