35. The purpose of clean finishing is to: • Maintain the grainline • Prevent raveling/fraying • Prevent stretching • Improve/enhance the appearance

36. Grading/layering is: • A small cut into the seam allowance almost to the stitching line • The cut edge of the fabric pieces • Trimming each layer of a seam allowance in varying amounts to reduce bulk • An extra thickness of fabric used to provide shape
