Minnie, you don't need to buy those expensive cards to store your stash. I fold my fabric salvage to salvage, then start folding fabric into segments approximately 26 to 30 inches long. Keep folding till all the length of fabric is folded. Then fold in half again or in thirds (whichever gives you the measurement you want). End of with a pc
8x22 1/2. Then fold in half again ending with a pc 8x11.
Then just stack them up on your shelves with the last folded edge facing you....nice and neat with no added charge.
