As has been said, aurifil 40 weight 2 ply thread that can be used for hand quilting is not coated with a wax like other hand quilting threads. I love aurifil thread for piecing, but much prefer waxed quilting thread for hand quilting. It doesn't tangle and knot easily and is much easier to thread. My favorite thread, and I think I have tried them all, Is YLI hand quilting thread. Needles also make a difference. Hiroshima Tulip betweens are the very best hand quilting needles. The eye of these needles is not stamped like other betweens so there aren't sharp edges or burrs to cut and shred your thread. Choosing the best tools and materials makes the task much more enjoyable and satisfying.
edit. Just realized you are using Aerofil thread and I didn't know there was such a brand. My search doesn't show that it comes in hand quilting thread, just quilting thread, but I may have missed it. I don't know the quality of this thread. It sounds suspect for hand quilting.
