The free arm provides around 16 cm of space to the right of the needle for exciting projects and limitless creative freedom. Sew at speeds of up to 900 quick stitches per minute, and your sewing projects will be completed in no time. Thanks to the BERNINA Free Hand System (FHS), you can raise or lower the presser foot using a knee lever (optional accessory). There are many different stitches that you can customize individually, making it quite challenging to choose a favorite. The semi-automatic needle threader makes threading easier than ever. Just a few simple steps, and the thread is in place. With the Buttonhole Slide Foot #3A, you can sew as many perfectly equal-length buttonholes as you like. You control the length.
