Thread for Serger

A serger offers a range of techniques not possible with a standard sewing machine. From professional garment construction to decorative rolled hems, your serger can handle it all. The key is using the right thread in the right position. Needle threads need strength, while looper threads need coverage and softness. By mixing different threads in your loopers and needles, you can create everything from invisible seam finishes to bold decorative edges on napkins, tablecloths, and garments.

For General Sewing

Thread for everyday serging, including garment construction, seam finishing, and edge treatments. Professional results with soft, comfortable seams.

★ RECOMMENDED

For general serging, use Woolly Nylon in your loopers and a strong polyester in your needles. Woolly Nylon is a soft, stretchy textured nylon thread that fills in the spaces between stitches, creating smooth, professional-looking edges. It's comfortable against skin and moves with stretch fabrics rather than restricting them. Use Perfection or Unlimited Universal in your needle positions for strength and durability.

For Decorative Sewing

Thread for decorative rolled hems, decorative edges, flatlock seams, and other techniques where your stitching becomes a design element.

For decorative rolled hems and decorative edges, thread your upper looper with Pearl Crown Rayon, Candlelight, Jeans Stitch, or Variations. Pearl Crown Rayon, Candlelight, and Jeans Stitch are all 12 wt. heavyweight threads that create bold, defined stitches. Pearl Crown Rayon adds lustrous sheen, Candlelight brings metallic sparkle, and Jeans Stitch delivers a matte finish. Use Woolly Nylon in the lower looper and a standard thread in the needles.

Real sewists, real results. Here's what fellow serger users say about their thread choices:

Woolly Nylon has been my go-to thread for burp cloths and receiving blankets for 20+ years. I put it on my serger loopers and adjust to get a wide, close stitch. It finishes the edges beautifully.

Pearl Crown Rayon creates gorgeous rolled hems on my cloth napkins. The sheen catches the light beautifully, and the thread runs smoothly through my serger.

Variations adds beautiful dimension to my decorative serging. The color changes at perfect intervals and the thread handles my serger's speed without issues.
