The Warm Company's Lite Steam-A-Seam 2 Double Stick Fusible Web is pressure sensitive and will produce a temporary hold on applique and other fabric materials. Reposition as needed until you are ready to iron. After you have fused the Lite Steam-A-Seam 2 Double Stick Fusible Web, the bond is permanent and machine washable. The Lite Steam-A-Seam is half the weight of normal fusibles and is ideal for delicate fabrics like lace, ribbons, and trim; it won't gum up your needle when sewing. Steam-A-Seam includes five 9" x 12" sheets.
