Abstract: The improved ruffling tape includes a heat fusible, flexible, resilient, elongated strip of thermoplastic or the like, to one side of which is a pull string loosely secured thereto, as by spaced stitches along the length of the strip, which stitches run over the string and into the strip. The strip can include the heat fusible material, if desired, only on the side opposite that bearing the string. The string has one end thereof anchored thereto, as by a knot which does not pass through the stitches. The The string may have a slip covering of silicone or the like. In accordance with the method, the strip is heat fused to one side of a fabric, with the string and stitches exposed. The fabric is then ruffled by pulling the free end of the string, with or without simultaneously pushing said fabric toward the tied end of the string. When the desired ruffling is obtained, the free end of the string is tied off against the adjacent end of the tape to hold the ruffling in place.
