The process of adjusting cloth by folding up a cut edge, folding again and sewing it down. The then encloses the cut edge so that it won’t unravel.
Heddels explains Hemming
Hems are used to give a garment a more finished look and to prevent the fabric from unraveling. Jeans are usually hemmed in the factory with a chain stitch, a stitch that pulls slightly on the denim and creates an attractive roping effect on the hem. However, this type of hem requires a specialized machine that most tailors do not have.
Because of this, many people who want to hem their jeans will use a method called European hemming that involves folding the pant leg up to the desired length and sewing just below the original seam to maintain the look of a chain stitched hem.
