Spray n Bond Fusible Adhesive is a iron-on, no sew adhesive for fabric. Use it for appliqué pieces, home décor, costuming and crafts! Tips: For best no-sew results be sure to have even coverage of spray to the edges of your appliqué. If sewing is desired, use a light coating of Spray n Bond Fusible Adhesive. A medium or thick coating of Spray n Bond Fusible Adhesive yields a no-sew, stiffer fabric, perfect for fabric sculpting and mixed media.
