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.
