Selahquilter welcome aboard. I don't think I'd try it without a presser foot. I think you need a darning or embroidery hoop if you're not going to use a foot. You can adjust for very light or no pressure on the presser foot and raise the plate above the feed dogs for FMQ on Touch & Sews. I've only experimented with FMQ once on mine and it was the regular foot. I was able to make it work enough to prove you could do it but you'll probably want to find a free motion or darning foot for your machine.
Sew-Classic.com carries them.
