Add the ultimate sparkle to all of your decorative projects. Sulky Sliver thread is a thin, flat, ribbon-like foil that is laminated with polyester, making it brilliantly reflective. Sliver thread works perfectly on sewing, serging and knitting machines, as well as for handwork. It does not fuzz, fray or shrink. Colour: Multi-Color Pastel, 250-yard spool.
