Let me look into the stickers. I'm more familiar with those on RedBubble than I am on Teepublic. What background would you prefer, they should be the same colours as the tshirt options.I would a totally buy a sticker, too, but don't care for the teal blue background. Anyway you can change the default background?
I'm cleaning up the artwork tonight, and I'm making a red one for those of us with the fast colour!
