Which seam finish involves encasing the raw edge for a neat finish, especially on sheer fabrics?

• A. French seam.
• B. Overedge seam.
• C. Flat-felled seam.
• D. Mock French seam.

Answer: (A)

The main idea here is finishing the seam so the raw edge is hidden inside the seam itself, giving a neat, delicate finish for sheer fabrics. A French seam does exactly that: you sew the fabric with wrong sides together using a narrow seam allowance, then trim and press, and finally sew again with the right sides together. This closes and encloses the raw edge within the seam, so no frayed edge or stray threads show on the finished garment. It’s especially good for sheer fabrics like chiffon or organza because it provides a clean, nearly invisible inside finish that respects the delicate, transparent nature of the fabric. Other methods don’t achieve the same encasing effect as effectively. An overedge (serged) finish wraps the edge with a stitch around the outside, which can be bulky and visible on sheer fabrics. A flat-felled seam folds and encloses the edge but creates a thicker, more substantial seam that isn’t ideal for light, delicate fabrics. A mock French seam aims to imitate the look of a French seam but doesn’t always provide the same fully enclosed edge, making it less reliable for sheer fabrics.
