I taped some of the non skid shelf rubber stuff to bottom of one peddle that kept scooting away. My featherweights have that type of buttons on it, set them on the non skid shelveing stuff. Helps if you don't have to chase them around. Which by the way, that non skid stuff comes in handy for a lot of things in quilting. Put it under machine to absorb some of the vibration on the older ones. Quiets them down.
