Which technique creates a reinforced end of a seam to prevent unraveling?

• A. Backstitch
• B. Overstitch
• C. Tacking
• D. Basting

Answer: (A)

Backstitching locks the threads at the start and end of a seam to prevent unraveling. By stitching backward over the initial stitches and then continuing forward along the seam, you create tiny reverse stitches that anchor the thread turns, so the seam stays secure even if pulled or stressed. This purpose-built reinforcement is what makes backstitch the best choice for finishing seam ends. Overstitch runs along the edge to prevent fraying but doesn’t lock the seam ends; tacking and basting are temporary holds for positioning fabric before final stitching.
