This stack of 9" square linings will make 6 pot holders. Included are: 12 - 9" squares of Warm Company's Warm & Natural Cotton Batting 6 - 9" squares of Warm Company's Insulbright insulated lining These materials have already been "prewashed" (hot water wash--no soap; hot dryer dried) and are ready for you to use with your pot holder fabric. Both of these linings were made in America and have been stored in a smoke free, pet free environment. The Warm Company (manufacturer) provides this information about its products: "The perfect soft, warm, needled cotton batting for quilts, crafts and wearable arts. Warm & Natural® will not separate or bunch, and contains no glue or resins. Can be quilted up to 10" apart. Gives an antique look and dyes easily. Strong, durable, unbeatably soft, bright, balanced and clean. Shrinkage will be about 3%." "The Warm Company is pleased to present Insul~Bright, a needle-punched, polyester, insulating material ideal for home sewers and crafters. Pot holders, oven mitts, and casserole covers are all popular projects made functional and safe with Insul~Bright. Insul~Bright consists of hollow, polyester fibers needlepunched through a nonwoven substraight and though a reflective, metallized, poly material. The needled material is breathable and won’t break down with washing. The hollow fibers resist conduction while the reflective, metallized, poly material resists radiant energy. The energy, hot or cold, is reflected back to its source."
