Before I got my walking foot, I quilted 2 baby quilts with my regular pressure foot and it worked fine for straight line quilting. The only issue is that your layers may shift a little since the bottom one next to the feed dogs will move quicker than the top layer next to the pressure fooT--but if you use lots of pins or basting you can do it just fine. For some reason I think I have seen the term darning foot used interchangeably with quilting foot--is it a round foot? Might work just fine for FMQ but am not sure.
