My husband has made a 1/4" plywood template for the floor under my sewing machine that holds my machine pedal in the correct position. The template is a rectangle with a space cut out of the front for my pedal to slide in exactly where I want it. It's a simple and reliable solution. The back of the plywood goes all the way to the wall so it's impossible for my pedal to slide back. I have another one on my Tiara sit-down quilting machine.
