thanks for that great web site - perhaps it may answer my problem as to why my thread sometimes knots up when I am hand quilting. I can go for several needles, then whamo! I get one of those awful knots. Sometimes they can be unraveled, but not all of the time and I end up cutting it off or burying it in the quilt. I use beeswas, thread heaven but no, it keeps knotting. Maybe I make the thread too long - I do not know. Anyone else out there have the same problem?????
