To do loops or other FMQ you use a "darning" or "embroidery" foot and drop the feed dogs.
I used to quilt on the diagonal or come along the ditch with a wavy stitch but am moving away from that more often and doing some type of all over FMQ. Especially for "fat quarter" type quilts that don't have any special design in them.
