Our Microfiber Polyester pillow shells are made from 100% polyester fibers that have been processed super fine to a super soft microfiber. This material comes in white color. This fabric is cost effective and therefore great for school art and sewing classes to practice painting, shaping, sewing embroidering and heat transfer vinyl. These pillow shells feature a 4" wide opening for easy filling. Easily filled by hand or machine. Must be sewn closed. These are shells only, stuffing sold separately. Recommended Sublimation Settings: 60 seconds @ 400F, medium pressure. Parchment paper is recommended to help avoid print coming through the other side. Machine washable and dryer safe (use gentlest cycle and lowest heat settings).
