you can get some pretty good deals on ebay, especially people who are clearing out stashes. No big deals at the e-bay stores, but they often have interesting yarns. Don't forget to figure in the shipping when you bid. I just picked up about 10 skeins of wool-ease for $16 (that's with the shipping).
Joann's on line was selling wool-ease for $1.99 a skein which in my area is a really good price. It's a nice, easy yarn to work with, washable and lots o'colors.
Congrats on your new talent. It will give you many years of pleasure.
