InsulBright sewing material (palm harbor)

Do you have any Insul-Bright insulation crafting / sewing material ? I'm trying to make some custom oven mitts for a family friend who has limited use of his hands, This is supposed to provide heat resistance. Probably need only about 1/2 yard, but if you have more and are willing to gift it, I'd be most appreciative. Can pick up anywhere from Palm Harbor to Clearwater to Largo
