I love YLI and Coats & Clark. My hand quilting group has been meeting for 40+ years and some of the members like to wax their thread. I love the waxed thread because it never knots. Melt Gulfwax in a coffee can in a pan of water. Remove from the heat. Drop in the thread ( leave a piece of thread loose so you can unwind it). When the bubbles stop, remove the thread and let it dry. It works really well. The wax can be kept for the next time you need it.
