Woolly Nylon Metallic #315 - Light Blue Cone

Woolly Nylon is a textured thread made from continuous nylon filaments that are crimped and heat-set to create a soft, stretchy, and fluffy feel. Unlike traditional threads that are spun or twisted tightly together, Woolly Nylon is designed to expand and move with your fabric. That means when you use it in the looper of your serger, it provides beautiful coverage, a gentle finish, and plenty of stretch, making it perfect for garments, activewear, or any item that needs to flex and feel soft against the skin.

Threading Woolly Nylon through your serger's loopers requires a little extra care, but it's simpler than it sounds. The most common method is the tie-off technique: cut your current looper threads, tie on the Woolly Nylon, and gently pull it through the thread path. Just before the knot reaches the looper's eye, snip it and thread the last few inches by hand. Because Woolly Nylon is soft and textured, this method helps prevent tangles, allowing you to sew faster without frustration.

Sewists love using Woolly Nylon for creating soft, full rolled hems that stand out. When used in the upper looper of your serger, it expands to fill the edge, giving your hems a beautifully finished look with added texture and color. It's particularly popular for projects such as napkins, children's clothing, activewear, or whenever you want the edges to shine. With over 60 colors available, you can match or contrast your fabric to create a clean edge or a bold, decorative accent that makes your work look polished and personal.

Woolly Nylon has excellent stretch and recovery, making it perfect for garments that need to move with the body. Its soft, textured finish creates smooth seams that feel gentle against the skin, which is especially useful for activewear, loungewear, children's clothing, and lingerie. Because the thread expands as you sew, it won't pop or cause tension in the seam, even on tight-fitting knits.

Use regular polyester serger thread or QuiltMaker in your serger needles when using Woolly Nylon in the loopers. The needle positions need strong thread that can handle the speed and tension of serger stitching. Woolly Nylon is specifically designed for loopers where it spreads and relaxes to cover seam edges beautifully. This combination (polyester in needles, Woolly Nylon in loopers) is the standard setup for most garment serging and creates professional-looking seams with excellent stretch and coverage. The thread color in your needles can match your fabric since it will mostly be hidden by the looper threads.
