SCHMETZ Chrome Professional Grade is the perfect sewing partner. Chrome resists heat and wear. Chrome will stay cool longer with less stitch distortion and aids the thread to pass through the needle eye with less friction and less heat build-up. Chrome also allows the needle to pass through the fabric with less resistance. Use with rayon, polyester, and other specialty embroidery threads. The special scarf, widened groove, and enlarged eye protect fragile threads and guard against excess friction allowing trouble-free embroidery and decorative stiching.
