I have the Start/Stop button and like using it versus using the foot pedal sometimes. I don't have carpet on my sewing room floor and haven't found a way to keep my foot pedal from moving around. I have to put something between it and the wall to keep it from not moving. I've tried everything else but just use the Start/Stop button so then don't have to worry about the foot pedal moving around me. I wish Janome made a larger foot pedal and that may stop my moving pedal.
