Insul-Bright 22 1/2in

Insul-Bright is a versatile, needle-punched insulated material that adds heat- and cold-resistant properties to sewing and craft projects. Made from polyester fibers needle-punched through a reflective metalized polyester film, it is breathable, durable, and machine washable. The fibers resist heat conduction, while the reflective film directs hot or cold energy back to its source. Perfect for pot holders, oven mitts, casserole covers, lunch bags, and more, it can also be used in apparel, soft books, and pet toys (note: the film makes a crinkly sound). Not recommended for microwave use.
