I have purchased them in 3 different sizes. I like the largest size for bulky fabrics but cut them in half for regular quilt fabrics using an old office type paper cutter. I have put up to 8 yards on one "card" and they look just like mini bolts of fabric. I have gone through 1 pkg of each size but mainly cut the large one, as I said. Remember how the newspaper boys rolled the ends of the newspaper before they threw them on your porch? Well, it works pretty well for fabrics if you don't stretch them too much.
