GÜTERMANN Denim Thread is a robust polyester jeans thread made for strong seams and decorative topstitching on denim, canvas, and other mid-to-heavy fabrics. This 100 m (109 yd) spool in Grey is suited to jean repairs, hemming, and visible stitching lines where you want a classic denim match. Stitch a short test seam first and adjust tension or stitch length to keep layers flat and help prevent skipped stitches.
