My favorite stitches for quilting in the ditch are what I call the EKG stitch ( zigs to one side, then takes a straight stitch, then zags to the other side ), and the serpentine stitch ( which is just a wavy line). I vary the width and stitch length depending on what fabric and batting I am using (do a test sample). They are probably in with your utility stitches--not the fancy decorative stitches--if your machine has separate menus. Even my most basic machine has the EKG stitch in the mending stitches. I seldom use a straight stitch because every slight wobble is so obvious. The two I mentioned are decorative and hide the wobbles nicely.
