Applying Shrink Tips
Lacing tips are sold by the foot and are actually a shrinkable tube.
1/8"diameter before shrinking
Cut a piece of tubing about ¾" long. Using a needle and thread (contrasting thread used for illustration purposes, you'll probably want yours to match!) bind the end of a lace, do not cut the thread! 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.
