I've said it before and I'll say it again...you can never have too many project bags. Or hooks!
If you're a veteran crocheter, why not freshen up your hook stash and get a new bag in the process? If you're a beginner--the bylaws written by the Official Crochet Council of the Universe dictate that you are required to have this particular bag and hooks in order to legally crochet...
I kid. There's no Official Crochet Council of the Universe. But if there was, they would want you to have these.
