The last all-purpose foot has a long history with BERNINA. For many years it was the only all-purpose presser foot, designed for models that had simple, forward motion stitches. The sole of Zigzag Foot #0 has only one small indentation behind the needle opening to accommodate stitches that are formed while only moving forward.
Foot #0 available with a 5.5 mm needle opening and is more limited than Reverse Pattern Foot #1/1C/D and Clear Foot #34/34 C/34 D. It is not designed for reverse-motion or compact decorative stitches but works perfectly when sewing simple stitches. Look at the practical stitch menu for the type of stitch that works with Zigzag Foot #0.
