The 1/4" presser feet really don't work with the wider feed dogs because they don't engage that right feed dog. We eliminated that problem by using foot #34C or #34D which covers both feed dogs. When sewing a 1/4" seam, we bump the needle to the right 3 bumps and guide the fabric just inside the feed dogs, or 4 bumps and guide the fabric along the outside of the presser foot.
