This is an interesting point. When I hand quilt I usually use a 40 weight cotton thread & don't bother running it through my beeswax.....about 10 years ago....everyone told me...you MUST run your thread through beeswax so that it doesn't tangle..... I still have the same BLOCK of beeswax...I'm still hand quilting (usually with a 40 wt but sometimes lighter or heavier)
