What does Clean Finishing prevent on the seam allowance?

Clean finishing is a sewing technique specifically designed to prevent the raw edges of fabric from fraying. When fabrics are cut, especially woven materials, the threads can begin to unravel, leading to an unfinished appearance and potentially compromising the integrity of the seam. By employing methods such as zigzag stitching, serging, or binding the edges, clean finishing secures the fabric threads and keeps them from coming loose.

While preventing fraying is the primary focus of clean finishing, other aspects like preventing wrinkles, stretching, or ripping are more related to different sewing techniques or fabric handling practices. Ensuring that the edges are neat through clean finishing contributes to the overall durability and aesthetics of the final garment, while addressing fraying is crucial for maintaining the structure of seams over time.
