Have you heard about Zazzle?
Zazzle's this pretty neat website where you can custom design your own items, and you can also open a storefront selling your designs. Cafepress works the same way, and both communities are a cool way to explore a LOT of interesting designs or make something for yourself that you can't find anywhere else.
A few of our team members have opened shops on Zazzle, check them out!
