King Tut is very nice thread. I have used it for hand quilting on my Grace Z44 Pro hand quilting frame. I was lucky and found some partial spools for sale at a quilt shop that long armed quilts and sold King Tut threads. The spools had about 1/4 of the thread on them, and sold for $1.00 each. I don't think that it was any better than some of the other quality threads I have used before, but it was nice to use.
