An overlock stitch or a merrowed edge is an overedge seam that finishes off a raw edge on a variety of fabrics, or attaches/edges two pieces of fabric together. An overlock sewing machine that cuts the edges of the cloth as it is fed through the machine is called a serger, although some are made without cutters. Sergers are used both in an industrial setting and in the home sewing market for edging, hemming and seaming. Overlock stitches can also be extremely versatile, as they can be used for decoration or reinforcement.
