This well-built, robust machine is a serger but unlike most sergers, it has several choices of styles and widths. You can use as many or as few as you desire. It can also be converted to sew a single chain stitch or a double coverstitch that are both great for those who sew with knit fabrics and appreciate a professional finish. This machine is in excellent condition, clean and ready to go. You can email, call or text me at (236) 562-6365 (local #)
