I use the SITD foot but I offset my needle just one click to the side so I'm stitching NEXT to the ditch. But I wobble and veer so sometimes it IS in the ditch, other times it ends up a little further away than I'd like it.
But my quilts are family gift quilts so I don't fret. Nobody will notice or care if I wobble around. I do practice and try to make each one better than the last but that's more for ME than it is for the recipient of that particular quilt.
