Polyarn is a premium “woollie-like” texturized polyester thread. Polyarn has excellent elasticity, recovery, and flexibility, which makes Polyarn the top choice for garment construction with sergers and overlock machines. Because Polyarn is 100% polyester, it has a higher heat resistance than woollie nylon threads. These beautiful colors are colorfast and can be commercially laundered without risk of fading. With its excellent coverage, Polyarn can be used for simple hems or fancy stitching.
