Zigzagger, for Singer 301, 400 & 500 series
Thiis original Singer zigzagger attachment uses cams to provide zigzag and other decorate "fashion" stitches. For use on the 301 and 404 straight stitch machines, it moves the fabric back and forth since the needle cannot be moved. This zigzagger will come with the original set of cams, attachment screw, and instructions.
