BOSAL-Poly-Therm Fleece. This heat reflective fleece is perfect of a variety of home crafting needs: pot holders; oven mitts; tea cozies; wine caddies; lunch boxes; quilts; apparel; stadium blankets; slippers; window covering and much more! White fleece on one side allows for machine or hand quilting with the dimensional effects we love and the silver lining on the other side actually reflects heat back to the source allowing for use in homemade coolers and warmers. Constructed of 100% polyester fleece and 100% polyethylene film. NOTE: to use as hot mitts or pot holders: a layer of cotton batting is recommended as a shield between the outer fabric and the Poly-Therm Fleece (extreme heat will melt fleece and film). This package contains one 62x36in piece.
