Spoonflower is now offering (in addition to the regular quilting-weight cotton) a heavy upholstery fabric and a linen/cotton blend fabric in a tea-stained antique color.
Remember? This is that service that lets you design your own fabric, and they'll print it for you? They host that design of the week contest I recently won.
Anyway, if you have an idea but are worried about the execution, maybe I can hook you up with a custom-made design. E-mail me!
