Sulky Heat-Away Clear Film can be used as a topper or stabilizer on all fabrics that can withstand iron temperatures of 260-300 degrees (similar to a cotton setting on most irons). It is perfect for computer-embroidered lace, cutwork, Battenberg lace, free-motion thread lace, and 3-D thread appliqués. Heat-Away Clear Film removes easily by pressing with a hot iron until all the film has melted and formed little balls. Then, you simply brush away the remaining particles.
