Strong, durable stitching for leather goods requires a specialized type of bonded thread, typically made from nylon, polyester, or linen. These threads are designed to withstand the stresses of sewing thick, tough materials and resist abrasion, ensuring the longevity of the finished product. For example, bonded nylon is a popular choice due to its high tensile strength and resistance to rot and mildew.
The use of appropriate stitching is crucial for the creation of durable and aesthetically pleasing leather items. Selecting the correct fiber type and thickness contributes significantly to the structural integrity and overall quality of leather projects, from footwear and upholstery to bags and accessories. Historically, linen thread waxed with beeswax was the primary choice for hand-sewing leather. The development of specialized machine threads has streamlined leatherwork and enabled mass production while maintaining high standards of quality.
