I have a piece of wood, approx 8 x 6 inches to which I have glue shelf liner (that rubbery textured kind) on both sides, It keeps the wood from traveling around the floor and keeps my foot pedal in place as I sew. Additionally, it raises the foot pedal up just about 1/4 to 1/2 inch, which prevents my accidentally stepping on it before I am ready to sew.
