Not to get off the subject but, you made me think of another body part. I had a happy accident. I still use a presser foot and I happened to put an old Whitmans sampler tin on the floor in front of my presser foot. It lifts my foot up just enough to use the foot pedal without constantly
raising your foot. You are only pushing down. Anything the right height for you would work. I am on a rug so nothing scoots away. Love it.
