Imported made from spun polyester. 24,000 yards per cone. 165 mm x 100 mm round. Bobbin thread is specifically weighted for machine embroidery. Use this product to reduce bulk, to keep your stitches flat, to reduce lint build-up, and to keep your design pliable. This is an ideal lightweight thread for machine embroidery or machine basting. When bobbin thread is used for machine embroidery, it allows the back of the embroidery design to be much less dense than the front of the design.
