My family has always tossed our quilts in the washing machine and if it's nice - dried them outside. If not they go in the dryer. No prewashing of fabrics. We feel quilts are to be used and enjoyed. I made a baby quilt for a recent shower gift the MtoBe said she was going to frame the quilt. I told her to use it on the floor and then toss in the machine if it wears out I'll make her another one LOL
