This serger is a must-have because it sews and finishes seams at the same time, while trimming away the excess seam allowance. Professional looking seams, seam finishes and 1,300 stitches per minute speed make this a real timesaver. You can use 2 threads, 3 threads, or 4 threads for a wide variety of stitch combinations. The 6 different stitch types ensure the perfect stitch, regardless of the project: blind hems, rolled hems, flatlocking, finishing raw edges and sewing seams. The color coded threading system has an easy-to-read diagram right on the machine to make threading effortless every time.
