I have been selling thread now for 15 years and in my opinion, Isacord is still the best. This is 40 weight polyester embroidery thread. It is strong, colorfast, and comes in 400+ beautiful colors. Our customers use this thread for Embroidery, Quilting, Long Arm Quilting and sewing. This is the exact same thread that sells in retail stores for more than $8 per cone. After you purchase the thread, just send us a note with your list of thread colors and we will send it right away
