I used cardboard and cut it to 12 inches x 7 inches and folded my fabric in half and rolled it on them. Like you would see in the stores. I secured them with a pin, but the idea of a bobby pin has now crossed my mind. Much cheaper and now I can all my fabric standing up! I just noticed to today when I went to the Dollar Store that they have poster board like stuff which has foam between the two layers. That could be a great alternative too I would think?
