My husband and I were coming back from Florida and I wanted to stop at Foust textiles in Kings Mountain NC. It's a big wharehouse (I could go crazy in there) bolts and bolts of fabric and all kinds of sewing stuff.I bought a bolt of 110" wide for backing.bought thread and quilt kits that were cut out and in packages.LOVE that place. Only trouble I don't get to go there much.
You can go there on line , but I really don't know if they sell to individuals. I have a small business and when I call them they ask for name of business. But if you know someone maybe you could use their business name. Only bad thing you do have to buy the whole bolt. But it's good prices.
