Some one suggested to me that you can get free yarn through this group, too. Makes sense. How many people have extra stash yarn they don't want, or have an elderly family member that passed, leaving a huge stash of yarn. If you're knitting for charity, people would be especially willing to give you their old yarn I bet.
