This is a good web site for several different reasons: <http://www.appleblossomquilts com> Connie Sue Haidle. She has a monthly newsletter, and a quilt pattern designing business and sells other quilt related items, BUT I'm giving it for you because in an earlier newsletter she had a wonderful system for storing quilts safely in a small amount of space. Hopefully you'll be able to get it. I gave my copy away.
Also some of the mail order stores, Nancy's Notions and Clotilde have acid-free tissue paper & quilt & textile storage boxes.
Sorry, This isn't short, but I get wound up. Cecelia
