I have about a dozen of these flat strips in varying sizes ranging from a foot square to 1x5 feet long. They're all about an inch thick. Stuffing is shredded fabric, and outer layer is thin plastic, the weight of a grocery bag. They would be excellent for lining a tub to make a feral cat shelter (covered with a sheet of thicker plastic and with straw at bottom), or to insulate boxes for shipments--which is what they were used for to arrive here. Pickup curbside in Nora.
