I absolutely am blown away by some of the fabrics on Spoonflower's site. I agree the price is prohibitive, but I would spring for some fat quarters for very special fabrics.
I have to wonder if down the road, as the business grows, the prices might come down. Printing small amounts of fabric must be very expensive. But for now, we really need to know how colorfast the fabrics are. We need someone (preferably multiple someones) with experience to tell us!
