my neighbor asked me to advise on the very same matter--I called the owner of a LQS that collects and restores quilts. She said to find a location--like a bed is best, to lay the quilt out for show only--no direction sunlight, pets, etc. and to refold so no creases form about every 3-4 months. If the quilts have worn places, just fold them into the quilt so not seen. Best advice ever!
