Sulky Invisible Polyester Thread

Achieve the look of "magic" stitching with Sulky Premium Invisible Thread! This incredibly fine .004 monofilament is the preferred choice for quilters and sewists who want strength without the bulk. Unlike traditional nylon invisible threads which can be stiff or prone to melting, Sulky is made of high-quality polyester for a much softer, more flexible touch that is gentle enough for baby quilts and garments worn next to the skin.

This thread is heat tolerant and won't melt under a normal cotton iron setting. It performs beautifully in the bobbin and is an ideal choice for sergers as well. Best of all, it won't fuzz, fray, or shrink, ensuring your projects look professional for years to come. Pro Tip: Use "Clear" for lighter fabrics and "Smoke" for darker prints to ensure a truly invisible finish!
