I currently have a small craft business: I hand paint and stencil designs or sayings onto shirts or totebags. I really enjoy it, but I'm normally so busy with other things that I can't put all my efforts into it :(
If I had both the financial and time resources, I'd definitely go into making wire jewelry. It's something that I've always wanted to try! I'd also do batik cloth, more types of bags and clothing. I'd even branch into making home accessories and ornaments.
