I just use regular cardboard that I cut to fit my shelves. I built my own shelf with approx. 9 x9 bins ( some are not quite 9 x9 because I'm not the best builder in the world) and also my husband had to help with the screws . After folding and wrapping the fabric I stand them up . If you have a lot of fabric you can see what you have better than if it's stacked on top of each other. I would send pictures if I knew how to do it but I'm not good on the computer but I'm trying to learn more.
