Insul-Bright insulating thermal lining keeps things just right. It's ideal for crafters who want to make simple, practical projects for use in their homes and as gifts. It consists of polyester fibers needle-punched through a reflective metalized polyester film. This breathable material resists conduction and reflects radiant energy, hot or cold, back to its source. For hot projects, using cotton batting is recommended to absorb steam vapor.
