Shrink Tips or Lacing Tips is a clear shrinkable tube used to encase the ends of cord trim. It is an 1/8" wide before shrinking. Using a needle and matching color thread bind the end of the trim. Do not cut the thread! Cut a piece of tubing about ¾" long. Drop the needle through the piece of tube and tug gently until the cord end is well within the tube. Hold the tube close to a candle flame or hot iron; be careful not to touch either. The tube will begin to shrink and tighten around the cord. Let cool and cut off excess tube. Repeat with opposite end of cord. Shrink Tips. Clear shrinkable tube. Sold by the foot. Click the prompt below the photo for more pictures.
