The heat shrink lace tipping is a 3/32″ diameter tipping that you “roll” the ends of your lacing through. Then by applying heat to the tipping it shrinks around the end of the lacing forming a tight bond. We have found a lighter works great for this purpose. If you are using the poly lacing supplied at Corsetmaking.com, the trick is to heat to the point that the lace will actually begin to bond with the tipping forming a permanent seal. Neat stuff!!
Caution: Be sure to keep your heat source far enough from the tipping that you don’t discolor it… especially the clear tipping that can easily discolor if flame is too close.
