Add an elegant sparkle with Sulky Metallic thread - a round, twisted thread that is created by twisting and bonding a fine metallic foil around a strong core to create an exceptionally smooth, strong and pliable thread. It's even more thin than Diamant metallic threads! It is a joy to work with on sewing, serging, and knitting machines, and for handwork. It does not fuzz, fray or shrink. For use with a sewing machine, use a lightweight bobbin thread and a 90/14 needle. Made of 60% Nylon (Polyamide)/40% Polyester, 40 weight and 150 yards.
