When I called to ask about this item I was told that there would be approximately 20% flawed areas, and that most customers buy twice the needed amount. When I received it I could not find a single flaw. This is extremely nice material at an absurdly low price. It worked very nicely for a cockpit cover for my boat. The material is coated on both sides and a bit stiff, but not difficult to sew. I have a lot left over... perhaps I should build a tent?
