Which technique is used to prevent seam allowances from unraveling?

• A. Hemming
• B. Backstitching
• C. Seam finish
• D. Zigzag

Answer: (C)

Finishing the raw edge of a seam to prevent fraying is the key idea. A seam finish coats or encases the seam allowance so the fibers don’t unravel with washing or wear. This term covers methods like serging, a narrow zigzag along the edge, or binding the edge—techniques specifically aimed at protecting the seam area. Hemming finishes outer garment edges, backstitching merely secures stitch ends, and while a zigzag can be a seam finish, the general term that describes protecting the seam allowance is seam finish.
