Wonder Fuse is a soft, single sided, lightweight paper-backed fusible web, fine enough to bond with even the minutest fibers, ensuring edges are always clean and smooth. It is especially suited for appliqué in all forms and if the design is intended to be worn or laundered, apply zigzag or blanket stitches to the edges to ensure permanency. The lightweight construction of Wonder Fuse becomes virtually invisible between layers of fabric, adding neither bulk nor stiffness. This paper backed fusible web will keep your fabric soft and ready to sew. Wonder Fuse, Lightweight Fusible Web, 18" x 3 yards, by Clover.
