Kelly, try loosening up the tension of your quilt top and the King tutt should work better. I used to get mine so tight and have problems with the thread breaking. Someone told me to loosen up my quilt top (so you can poke your finger from the bottom of the quilt and you can grab the top of your fingers between the quilt), so I loosen it and my king tutt thread doesn't break as much. Now, I love quilting with King Tutt. I use the Guide, So fine (I like it on my bobbins), Omni, Fil-Tec Harmony is a great cotton thread, and I just ordered the Superior So Fine 40 Veriegated to try. I'm also going to try the Medeira Polyester thread next. I think it is good to have a variety.
