YLI Invisible Thread – Fine Polyester Monofilament for Quilting, Appliqué & Stitch-in-The-Ditch (Invisible Thread Poly & Topstitch #70/10, Combo Pack)

Let your fabrics shine with Invisible Thread Poly – the must-have polyester monofilament thread for quilters and sewists who want flawless, subtle results. Designed to virtually disappear into fabric, this ultra-fine thread is ideal for appliqué, stitch-in-the-ditch, free-motion quilting, echo quilting, and any project where the beauty of your fabric and design should take center stage. Unlike shiny nylon threads, Invisible Thread Poly features a special matte finish to reduce glare and blend seamlessly into backing fabrics without distraction. Each 1,500-yard spool ensures long-lasting use, while its strength and flexibility make it perfect for both home sewing machines and longarm quilting setups. Pair with Titanium-Coated Topstitch Needles (#70/10) and adjust your machine’s top tension (1.0–2.0 recommended) for smooth, break-free stitching. Invisible Thread Poly is the ultimate combination of strength, invisibility, and performance—your new go-to for professional quilting results.
