Pellon® 71F Peltex® I One-Sided Fusible is an ultra-firm, smooth, heavyweight stabilizer for accessories, crafts, home decorating, machine embroidery, and quilting. It is easy-to-sew, even when sandwiched in between other fabrics. Peltex® I will not flatten out or be distorted with steam pressing. It has no grain and can be cut in any direction. Most Pellon products have either a dot adhesive or a spray adhesive. The dot adhesive is on the rough side, where you can usually see the dot. The spray adhesive is the shiny side. When in doubt, take a small sample and test it covering both sides with a paper towel or fabric so you can ensure that you do not make any fusing mistakes.
