I say "sorry, I only make things for myself, friends, and family. I don't sell my handcrafts." I made some hot and cold ice bags as holiday gifts for work mates and a lady posted to my blog she wanted to buy some in animals shapes for children. I said, "great idea, but sorry not in the business." I think that would suck the joy out of it for me. I have a arm's length worth of project to do and no time, for things I'm not interested in.
