I forgot to tell you about Spoonflower!

Spoonflower is in it's Beta form. This little company is a custom fabric service. Here's what you do (right from the web site)

Love fabric?
Print something unique

• Spoonflower lets you print fabric from designs you upload to your own account on our web site.
• All your designs are private unless you choose to make them public. We will never sell, print, or share your designs without your permission.
• There is no minimum fabric order and no set-up fee. You can order a swatch for $5, a fat quarter for $11, or multiple yards at $18 each. Registration is free.
• At the moment, fabric choice is limited to 100% Bella™ cotton from Moda™, a maker of very high quality fabrics for quilting.
• We are based in Mebane, North Carolina, but ship all over the world.
• We are happy to have you here.
