I recently caused a small scrape/tear in my white vegan leather upholstery. It's only about 1/2 inch square, but would like to patch it. Service center can't do anything and said they didn't have any to sell to me. Local upholsterers don't seem to carry it. Does anyone know where I can acquire a small piece of the material to do it myself? Can I get it from the factory? Thanks very much.
