I bought a cone of CT tread and have used it exclusively for piecing for 6 months, and I've pieced a lot. It looks like the cone is the same size as it was when I got it so it is going really far. I used to use Coats & Clarks and I was forever getting out a new spool as they seemed to go so quickly. I really like Connecting Threads for thread as well as fabric. Their fabric is nice and more reasonable than quilt shop fabrics.
