Rug serging may also be referred to as overlocked stitching. Serging the edge of your carpet produces a look that seems hand-sewn, even though it’s mostly done by a heavy sewing machine, like binding. When it’s finished, a serged edge looks as though a thick fiber has been wrapped around the edge of the carpet continuously. Rug serging is often considered to provide a higher-end look than simple binding and is commonly seen on manufactured area rugs.
