If you rest the ball of your foot on the button that doesn't move, you just tilt the side of your foot over onto the button that does move to control the machine. It's very comfortable and easy to use that way.
But, I still prefer the electronic foot controllers from Jenny at shop.sew-classic.com - so smooth and they don't get hot. Those bakelite controllers get hot when you're doing free-motion quilting, unless you're running it wide open.
