What is topstitching in sewing?

Topstitching refers to the technique of sewing a row of stitches on the exterior of a garment, typically for decorative purposes. This stitching is visible from the outside and can serve to enhance the overall design of the fabric, provide detail to seams, or even create patterns. In addition to its decorative function, topstitching can also offer functional benefits, such as helping to flatten seams, which is why it is often used in various sewing projects.

While topstitching primarily serves a decorative purpose, it can also reinforce seams, although this is not its main intent. Therefore, it stands apart from other types of stitching that primarily focus on structural support rather than aesthetic appeal. The technique itself can be varied in style, with different thread types, colors, and spacing, allowing for versatility in fashion design and garment construction.
