I have two book shelves in my sewing room, which is very crowded. I file my fabric by seasonal, plain colors, etc. on the shelves. I have also added roll down window shades to the front of the shelves to help keep dust off the fabric. I sprayed adhesive to the fronts of the shades and put white felt on them. When they are down I can also use them as a way to audition my blocks. When I need fabric I can just roll up the shades. Works well.
