topstitchinga
Topstitching is a decorative and functional sewing technique where stitches are placed on the outside of a garment or textile. The primary purpose of topstitching is to emphasize design lines, add visual interest, and reinforce seams. It is typically done with a needle that is slightly larger than the one used for the internal seams and often utilizes a thicker thread or a contrasting color to make the stitches stand out.
The stitch itself is usually a straight stitch and is placed a consistent distance from the edge
Common applications for topstitching include jeans, where it's famously used to decorate and reinforce pockets and
