I bought a mat specially made for keeping your foot pedal in place about 5 years ago and I love it. I think I paid around $25 for it, but I didn't have to keep trying different things. It's perfect.It's plastic with some velcro on the top and I put velcro on the bottom of my foot pedal so it stays put. The bottom of the mat sticks to my carpet and doesn't move at all. Best sewing item I've bought!
