When is a backstitch used?

• A. To decorate the seam.
• B. To reinforce the seam by topstitching.
• C. To finish edges with a zigzag.
• D. To secure the beginning and end of a seam so it does not unravel.

Answer: (D)

Backstitching is used to secure the start and end of a seam so it won’t unravel. When you begin sewing, the first few stitches can pull loose if not locked in, and at the end you want the thread tied off so the seam stays intact. You achieve this by stitching backward for a few stitches, then forward, creating a strong lock at the ends. This technique is about anchoring the seam, not decorating it, and it’s different from topstitching (which adds a visible line along the seam for reinforcement or look) or finishing edges with a zigzag (which prevents fraying). So the purpose of backstitching is to prevent the seam from coming undone by locking the threads at the start and end.
