whether or not i'd toss a quilt into the dryer depends on a few things:
age. i'm finishing a quilt somebody started more than 40 years ago. no dryer.
materials used; fabrics; embelliments, etc.
intended use. if it's to be a show piece - whether on a bed or a wall - i'd avoid the dryer. if it's going to be used - especially for a baby or by a kid - it had better stand up to the abuse of a warm water wash and a trip to the dryer. i throw all the crib and kiddy quilts i make into the washer and dryer at least once as a test before i give them away.
