In lap seams, the edges are:

• A. Left out
• B. Rolled in
• C. Trimmed
• D. Overlapped

Answer: (B)

Rolling the edge to finish a seam keeps the edge neat and flat, with the seam lying smoothly without bulk. In a lap seam, the fabric edge is tucked inward toward the seam allowance and stitched close to the fold, so the edge isn’t visible and the seam sits cleanly against the body. This approach prevents fraying, maintains a low-profile finish, and works well where a smooth, unobtrusive edge is desired. Leaving the edge raw would cause fraying, trimming would shorten the edge and weaken the finish, and overlapped edges would add unwanted bulk and create a visible seam line.
