I just bought 1/2 dozen large spools of Glutterman cotton thread on sale and am so disappointed. I was using some of it to sew on the binding of my quilt and I got a knot in the thread about every other stitch. It was taking me forever and sometimes I couldn't get the knot out so had to cut the thread and restart. I tried running the thread through thread wax and even used a dryer sheet (which I heard about on this board) and nothing seemed to help. I finally switched to a poly thread and didn't have any problem. Anyone else have problems with 100% cotton thread for hand sewing. I'm thinking of taking it all back and buying the poly thread.
