Not only do you not need a stitch regulator, you dont even need drop feed dogs. It is even possible to FMQ without a darning foot. "Can't" is a bad word at my house. No regulator=you become the regulator. Feed dogs don't drop=either cover them or set stitch lenght to 0. No darning foot, use the smallest or clear foot you have and release the pressure on the foot. There is always another way to do everything.
