I do not hang my fabrics but do pull a green earth trick. I ask for the cardboard emptied bolts from my local quilting shop and then fold my purchased fabrics like they were at shop and rewind upon the bolts. My closet has a perfect height shelf for storing my yardages. Smaller fabrics are folded into shelves in another closet and scraps in a large basket on the floor which makes a warm decoration. I do hang my pieced quilt tops that I am working upon from day to day. They are not left there for more than a couple days however and the seams are always folded to the inside. Love new pizza boxes too--never a used one. I store blocks I am working upon in them.
