There are lots of places to sell your work, I've previously mentioned, papernstitch, etsy, and copious.
Today I"m here to tell you about storenvy. I just started using this site about two weeks ago myself, so I don't have a ton of feedback for you about sales. However, thus far it's been super easy to use, and it's FREE. That's right, they charge nothing, no listing fee, no renewal fee, no commission, no nothing. So why not give it try, right?
