Is polyester or cotton thread best?
Both polyester and cotton threads can be used very nicely for quilting as well as some specialty threads such as metallic. It is often recommended that for piecing you use the same fiber in your thread as the quilt fabric so that they will wear the same. However, for quilting, either one works very well. Polyester or specialty threads often add strength and sheen and come in a wider variety of colors. Natural fiber threads are still popular. They create softer stitches and have little give or stretch. Cotton Thread will wear and fade at approx. the same rate as cotton fabric while Polyester thread color will tend not to fade.
