No you don't use a walking foot for free motion quilting. Usually you drop your feed dogs so there is no tension on the fabric so you can move it around yourself by using your hands to guide it where you want it to go. You either use a special foot for FMQ on your machine or a darning foot. You can refer to your machine's manual, or google it. And there are lots of books and you tube videos out there. It's a world of it's own.
