I prewash ALL my fabric, the same way I gently wash & dry my quilts later, so have never had a problem drying them, & I have no place large enough, inside, to let a quilt air dry entirely, so have no real choice otherwise. I do agree, some people wash a quilt to death. Mine, on our bed, only gets a gentle wash, if hubby says it smells, as he has a super fine sense of smell (drives me crazy at times!), otherwise, it might get a little spot wash now & then,if needed. I don't wash a quilt when I finish it either, as all, except small charm pack quilts, have been washed first, so why wash it again, right... This method works for me & I have never had any problems in doing so....
