Whether you’re stitching leather belts, bags, or footwear, you can trust that the thread will stand up to daily use and exposure to the elements.

Applications in Leatherwork

The primary application of polyester filament sewing thread in leatherwork is for stitching leather goods. This includes crafting leather wallets, belts, handbags, and more. The thread’s strength ensures that even under tension, the stitches hold firmly, contributing to the overall durability of the product.
