Having just come back from the big Paducah Quilt Show, where I saw probably hundreds of "new" quilts and my guess is that NONE of them were washed after they were quilted. They were all NOT WRINKLED or whatever you want to call it. They were all very flat and smooth. However, the overall winning quilt was hand quilted. You can google to see a picture of it - I don't think I can put a picture of it on here.
