Woolly Nylon Metallic is our decorative serger thread made from textured nylon intertwined with metallic thread that stretches with your fabric. Woolly Nylon Metallic excels as a decorative looper thread in your serger, enhancing everything from sundresses to the charmingly decorative edges of tablecloths and napkins. Unlike spun thread, its crimped texture creates soft, comfortable seams that won't irritate skin and remain secure even after repeated wash cycles. Each cone contains 546 yards of thread.
