My walking foot has interchangeable soles - one specifically for straight stitching, one for edge or ditch stitching and one that allows decorative stitches. Mine is specifically made for Bernina machines.............but you might check and see if Brother has a similar featured-foot available, aside from their standard walking foot. Or perhaps a universal walking foot is available with a sole that would allow decorative stitching - just be sure it is for your specific shank (high/low)?
