Check posts 2248, 2771, and 2901 for fabrics from Seattle and Rockywoods. There are many other posts here from people who have tried other fabrics and concluded that it was a mistake. Currently Matt is the only supplier offering the correct fabric to the public. I speak as someone who bought the wrong stuff in the past and will not again – shipping delays and costs will soon be forgotten while your project, built well or badly, will stay with you.
