This is Bernina's long respected "workhorse" of a Serger style sewing machine. I purchased this machine new from a Bernina store in MA while taking classes. It was a duplicate of the machine I already had at my home in Maine. I am downsizing my textiles studio so it's time to pass this machine to a new owner. Features: Needle Threader Adjustable Stitch Length and Width Adjustable Presser Foot Pressure 3 Thread Serger 4 Thread Serger Differential Feed Rolled Hem See manual link below for the full description of the many stitch styles. This is truly the one serger for construction and edge finishes on stretch fabrics, upholstery fabrics, garment fabrics, includes the ability to easily and quickly gather, hem, and create seam finishes.
