The Overlock is a useful and versatile product for everyday use, that complements the use of sewing machines. It is ideal for seaming stretch fabrics, jersey or cotton as the density of the point it creates allows the seam not to deform or tear. The overlock also allows the sewer to perform three separate operations in one go: sewing two pieces of fabric together, discarding the tissue in excess, refining the seam with an overlock stitch. The fabrics are kept together without entangling.
