Loretta, the knee control is easier to use than the foot control because it stays put! I don't have one set up for my current machine, but I sew on an older model sometimes and I LOVE it! I am considering getting aconvertor set up for my current machine and cabinet. I have a thingy for my foot pedal, but I still chase it around on the carpet. I have tried other remedies, but I find them wanting. The knee control is always right there! :lol:
