Your idea is awesome. I have a closet I took out the hanging rods and blocked off with inexpensive bookcases I bought at WalMart. Then folded all materials larger than 1/2 yard around a regular piece of paper (8.5x11"). They stack beautifully, lay flat and show enough of the color/design to pick out what I want easily. Any fabric smaller than 1/2 yard is wrapped around 1/2 sheet of paper (5.5x4.25") which again lay nicely on the shelves. This gives me an easy guide for folding and costs little. I like card stock (65 lb) paper best but do not always have it and regular copier paper works just fine, too.
