GÜTERMANN Invisible Nylon Thread is a monofilament sewing thread that helps hems and attachment stitches blend in, making it useful when you do not want the seam to show. This 150 m (164 yd) spool in Clear is handy for quilting bobbins, beading, and attaching trims or appliqués while keeping the stitch line visually subtle. Use moderate tension, stitch a test sample, and avoid pressing directly with high heat to reduce shine or distortion of the filament.
