I plan to also start listing some of these products on eBay, but for now, here are my two shops of products I feel confident about.
My Printfection Store
Use this shop to buy anything on fabric -- t-shirts especially! Many colors available even though the previews only show white.
My CafePress Store
Use this shop to buy non-fabric items. Magnets (now in stock!), buttons, mugs, a clock...
I'll expand my offerings later, but here's what I feel good about selling so far. Yay! :)
