I have stored my fabrics in plastic crates, stacked 4 high and 4 wide (with the opening facing out). I put a piece of heavy cardboard (don't recall where I found the piece) on top to make a shelf. Then I purchased a sheet of styrofoam, covered it with flannel and proped it up in front of the bins of fabric. This forms my design wall as well as covering my fabrics from my full wall of windows. When I want to get to the fabrics, I simply slide the lightweight wall out a bit and voila!! I can get to all of my fabrics. This way I can sort by colors too.
