This product is useful in SO many projects. Perfect for insulating hot pads, BBQ and cooking mitts, ironing board covers, costumes, flat-iron or curling iron totes, and crafts. Also recommended for quilting, apparel, lunch bags, sleeping bags, wine caddies, stadium blankets, throws, window treatments and coverings (reflects heat source), place mats, trivets, oven mitts, throws and wraps for outdoor activities and sporting events. White fleece allows for machine or hand quilting with the dimensional effects we love and the silver side reflects heat back to the source allowing for use in homemade coolers and warmers. Constructed of 100% polyester fleece and 100% polyethylene film.
How to use heat resistant poly-therm batting: Use two ply of the batting. On a potholder, put the reflective side of the fleece against the wrong side of the fabric to line the palm of the pot holder or mitt. You should also add a layer of cotton batting in between Poly-Therm and the outside fabric to make for a more comfortable and thicker pot holder or mitt. Poly-therm is also a great batting to use as a lining in lunch bags and totes to keep food cool.
Note: At least one layer of 100% cotton batting is recommended with Bosal Poly-Therm Fleece when used for oven mitts, trivets, or potholders as a shield between the outer fabric and the Poly-Therm Fleece (extreme heat will melt fleece and film). When you purchase, you'll receive a 62" wide piece. 5.5oz Needlepunched batting with a heat and cold reflective metal coating 100% polyester 100% Polyethylene Film
