If you are needing to stock up on patch material Hobby Lobby is having a sale of all material at 30% off. I believe this is nation wide. They have in the St. Louis store on St Charles Rock Road several weights of pure cotton canvas material. They also have "drill" which is very tightly woven. When I checked out the clerk had actually given me 50% off!!!! I went to two fabric stores before checking HL and couldn't find the variety of cotton fabric that HL has!!!! ,,,,Ed
