Thanks for explaining that, it's good to know there is an actual reason for it.
I am just really annoyed about hanks right now because my lace weight Malabrigo is a big giant mess right now because of it being in a hank and then trying to hand wind it. I did it nice and slow, and steady and spent hours at it, and only got half a hank wound up before abandoning the rest.
Never buying hank-ed yarn again. In my experience it just hasn't been worth the extra hassle. :???:
