Had the same problem and then discovered the Martelli one. Your foot pedal will not move. I also got the one for my sewing machine and it is great. Machine stays put and even sounds softer rather than the sound on the wood table. You can find them at Martelli.com or at some of the other fabric stores (local or on line). An earlier post said she found it at Walmart. The foot one alone is cheaper than the one in Nancys Notions but there is a discounted price if you buy the machine and pedal one together. Martelli also sells them at the quilt/sewing shows if there is one coming to a place near you.
