At least one layer of cotton batting is recommended when using Insul-Bright as lining for potholders and other quilted items. Cotton is suitable to use as batting alongside an insulating fabric like Insul-Bright because it does not catch fire easily. For items you need to use with heat or flames, such as potholders or oven mitts, it would be best to use 100% cotton. Avoid using fabrics with synthetic fibers which could melt and blaze. Insul-Bright packaging comes with instructions on how to use the insulated batting material. But some experienced users of this excellent lining material have brilliant suggestions on how to use it for more efficient insulation from heat. For an oven mitt, you can use one layer of Insul-Bright with one layer of cotton batting. Place the layer of cotton batting on the side where you will hold the oven mitt to protect your hand from heat. The Insul-bright must be placed on the side that will encounter hot surfaces. It is also advised to use thick fabrics to cover the insulation material and cotton batting to add more protection from heat. When making a hot pad, you will need to put a layer of cotton batting on the side that would touch the table’s surface. The part that will catch the hot pot should have the Insul-Bright to help keep the pot hotter for a longer time. You can use two layers of Insul-Bright to make your potholders, oven mitts, and casserole carriers more heat resistant.
