Add an elegant sparkle to your creativity with Sulky Original 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 is a joy to work with on sewing, serging, and knitting machines, and for handwork. It does not fuzz, fray or shrink. Use a lightweight thread in the bobbin, either use a matching Sulky 40 Wt. Rayon Thread, Sulky Bobbin Thread or Polyester Invisible Thread. Our small spools are perfect for most projects, but you may want our larger spools for your most loved colors!
