Invisible Thread Poly is a very fine polyester monofilament thread designed for applications where you want your stitching to blend in. It’s ideal for stitch-in-the-ditch, machine appliqué, free-motion quilting, echo quilting, and any technique where the focus should stay on the fabric and design, not the thread.

Its matte finish minimizes shine, allowing it to disappear into a wide range of fabric colors and textures. The smooth surface and high heat resistance of polyester make it excel with both home and longarm machines, even during extended stitching sessions or ironing.

Invisible Thread Poly is slightly heavier than Wonder Invisible Nylon and, as such, has improved abrasion resistance and strength, helping to reduce thread breaks while working with layers, curves, or detailed quilting.

Recommendations for Best Use:

• Loosen top tension to 1.0-2.0 to prevent breakage
• Use a #70/10 Topstitch needle for home machines
• Use a #14 (3.0) needle for longarm quilting
• Pair with Precision in the bobbin for optimal stitch quality

Available in 1,500 yard spools and 7,500 yard cones.

Invisible Thread Poly is a versatile choice for quilters and sewists, especially when the thread isn't meant to be seen.
