You can buy it at JoAnn's. I have some white if you want it. Send me your address in a PM. It is 31 inches long and 29 inches wide doubled. It is what you would use on the bottom of a sweatshirt. I have had it for a long time and there are a couple of streaks across it where it was folded on a shelf, but I think you can work around it. It is yours if you want it.
