Woolly Nylon is the original serger thread made from textured nylon that stretches with your fabric. This fluffy looper thread provides exceptional coverage of seam edges on garments, lingerie, and swimwear, and makes for fantastic decorative rolled hems. Unlike spun thread, its crimped texture creates soft, comfortable seams that won't irritate skin and remain secure even after repeated wash cycles. The thread stretches with knits and four-way stretch fabrics without breaking, making it perfect for yoga pants, activewear, and any project that needs seams that move with the garment. Each cone contains 1,094 yards of thread.
