Product description

The Original Textured Nylon Serger Thread: Woolly Nylon

Woolly Nylon is a soft, textured nylon thread designed to be used as a looper thread for sergers and coverstitch machines. Perfect for knits, activewear, and rolled hems, it offers superb stretch and coverage.

Woolly Nylon makes sewing more enjoyable

Excellent stretch and recovery

Woolly nylon thread provides exceptional flexibility, allowing it to stretch an incredible amount without breaking. Once stretched, it returns to its original shape, making it ideal for seams that need to move with your fabric while staying strong.

Colors made to blend

With over 60 thoughtfully designed colors, our Woolly Nylon thread is made to blend into a variety of fabrics, from knits to cottons to tulle. We offer a range of colors to blend with soft pastels, neutral tones, and bold hues.

A favorite looper thread

In a serger, the looper threads wrap around the fabric edge, instead of forming straight stitches like the top threads, which offer stretch and coverage. Woolly Nylon is the perfect looper thread because it expands and fluffs up to create soft, full seams.

What is a textured thread?

Woolly Nylon isn’t spun or twisted like most sewing threads; it’s textured. This unique, fluffy texture provides excellent coverage over edges, giving your garments a professional finish while remaining soft on your skin, even after multiple washes.
