I use the Coats and Clark Dual Duty for sewing my quilt tops together. I have also used the Gueterman's 100% cotton thread as well. It doesn't go as far as the Coats and Clark and is more expensive than the Coats and Clark. I have been using the Coats and Clark as long as I have been sewing (40 years) and I haven't had any problems. I guess it's your preference and what you can afford. Don't use super cheap thread but a good quality. Just be careful at Joann's and pay attention to the price. Some of there Guettermans and Sulkey Threads are up there in price. Good Luck.
