Durable, specialized filaments are essential for stitching leather goods with a sewing machine. These typically consist of nylon, polyester, or linen, often bonded or braided for enhanced strength and abrasion resistance. A waxed or silicone-coated version provides smoother passage through tough hides and reduces friction, leading to less needle breakage and consistent stitch formation.
Selecting the appropriate stitching material contributes significantly to the longevity and aesthetic quality of leatherwork. Robust threads ensure seams withstand stress, preventing unraveling and maintaining structural integrity. Historically, linen and waxed linen were favored, but advances in synthetic fibers offer greater tensile strength and resistance to rot and mildew, especially important for items exposed to the elements. Correct fiber selection prevents premature wear and tear, contributing to the creation of durable and visually appealing leather products.
