Leather is really abrasive on fiber, so the wax helps keep your thread from fraying. Waxed threads are stronger and stiffer than unwaxed thread while retaining most of the thread's smoothness feel and vibrant color. This thread can sew anything that can be sewn with waxed nylon or polyester strings. For example: Leatherwork, awnings, sails, shoes, saddles, bags, brief cases, gun cases, and luggage, etc.
