A hem is the finished edge of a piece of fabric, typically found on clothing. It is created by folding the raw edge of the fabric and sewing it down to prevent fraying. Hems can vary in width and style, including straight, curved, or decorative finishes, depending on the garment design. In sewing, the hem serves both functional and aesthetic purposes. It provides a clean look to the garment while also ensuring durability. Different types of hems, such as blind hems or rolled hems, are used for various fabrics and styles, enhancing the overall appearance of the clothing.
