I have a storage container underneath my sewing table & it's against the wall. I put my pedal up against the container & it doesn't move because of the wall & the container. The foot pedal for my Juki is quite large though. I purchased a mat for my Bernina 820 & it works pretty well. I like the idea of buying a bathroom rug with the grip on the underside & that will probably do the trick. You also could try that rubberized grip pieces & somehow attach a piece to your foot pedal & that also might work.
