Why is it important to clip curves and notch corners when sewing curved seams?

• A. To shorten the seam.
• B. To create decorative texture.
• C. To weaken the seam.
• D. To allow seam allowances to lie flat and prevent bulk or distortion.

Answer: (D)

When sewing curved edges, the fabric has extra fullness around the curve that can cause bunching or distortion if left intact. Clipping small wedges into the inner curves releases that fullness so the seam allowances can lie flat and follow the curve smoothly. Notching corners releases bulk at the outside corners, letting the fabric turn cleanly and preventing corner distortions. Do this carefully, stopping short of the stitching line, so the seam remains secure. This technique is about making curved seams lie flat and look neat, not about shortening, adding texture, or weakening the seam.
