Which term is used for trimming seam allowances to different widths?

• A. Grading
• B. Trimming
• C. Seaming
• D. Serging

Answer: (A)

Grading is the practice of trimming seam allowances to different widths to reduce bulk and help seams lie flat, especially on curved edges. By shaving more material from the inner curves and less from the outer curves, the fabric stacks more smoothly and the seam doesn’t pucker. Trimming alone just cuts away excess without varying widths, seaming is simply joining fabrics, and serging finishes the edge (often with its own trimming) but isn’t the process of adjusting seam allowance widths. So, the term used for this technique is grading.
