INSUL-BRIGHT, a needle-punched, insulating material that is ideal for home sewers and crafters. Create projects like pot holders, casserole carriers, and oven mitts. The hollow, polyester fibers are needlepunched and breathable and won't break down with washing. The fibrous material resists conduction while the reflective mylar metalized poly films resists radiant energy, hot or cold. Won't break down with washing. Machine wash and dry. Pieces are sold by the yard and are 22" wide and 36" long. If you order more than one yard, the piece will be a continuous cut unless otherwise requested.
