I have vinyl flooring and have tried the shelf liner and mouse pad and it STILL wanders, The silicone hot pad might be an idea. I don't think I am coordinated enough to use the start/stop button on the Janome though might get used to it - after I had to do a lot of 'unsewing'. (I still catch myself trying to use the knee lift for power and how many hundred years has it been since I used a machine that ran that way?) Short of nailing it to the floor, I have no other ideas.
