It's been one week since I began putting items in the shop, and I have neglected the mass e-mail that I meant to send, or much of any other publicity at all. I have tried posting a few links in the promotions forums, and they are so busy that it's easy to get lost there. I think that listing items frequently will be the way to go.
Thumbnails of items are above. I haven't sold anything yet, but I'm having so much fun with this!
