Don't know if it's been mentioned or not, but I use one of those sticky car dash pads next to all of my machines. I have more than one set up at a time so I can move from one to the other with a minimum of hassle or share my space with my daughters. I put my scissors, pin cushion, screw driver, chopstick or "purple thang" on it so they are always close at hand. Sure stopped the problem of machine vibration knocking things onto the floor or worse yet, the trash can.
