Nice wool usually comes in a hank, which must be wound into a ball. Most of my yarn is Walmart, Hobby Lobby, or Joann's stuff in a skein. I like the acrylics for charity and baby knitting, but I'm also in love with Woolease wool/acrylic blend from Lion brand. I'll admit, I'm lazy and pull it directly from the skein. When it gets down to the end, tangles, and is hard to work with, then I'll roll it up into a ball out of frustration.
Welsh corgis are cool.
