Does anyone know what those board things are called that you wrap fabric around on your shelves? What dimensions, or type of material that could be possibly used to make them( don't have funds to buy them, or even a store to purchase them for that matter)? OR, even any ideas to use to keep fabric neat on my shelf? I did the folding thing, with the ruler, and its great. But I just want to be able to utilize the few shelves I have, more efficiently..
