What is the finishing technique used on the bottom edge of a clothing item called?

The finishing technique used on the bottom edge of a clothing item is known as a hem. A hem serves several important purposes: it prevents the fabric from fraying, provides a clean and neat finish, and contributes to the overall aesthetic of the garment. When a hem is applied, the raw edge of the fabric is folded under and stitched down, allowing the fabric to maintain its structure and durability over time.

This technique can vary greatly in style and complexity; for example, a simple double-fold hem is commonly used for casual garments, while more intricate hems like the blind hem or rolled hem may be employed for formal wear or delicate fabrics. Knowing how to properly hem a garment is an essential skill in sewing, as it directly impacts the quality and professionalism of the finished product.
