Where are welt seams used?

Welt seams are commonly used in the construction of garments and accessories that require durability and a polished finish, such as jackets, trousers, and bags. They involve a strip of fabric (the welt) being inserted into the seam, which reinforces the stitching and provides a decorative edge. This technique is also used in upholstery and leather goods to enhance both strength and aesthetics. Additionally, welt seams help prevent fraying and can add a waterproofing element to certain items.
