Hi Annie Pearl. I once saw a great hint for achieving the scant 1/4" seam. I don't recall where but it works so well and can easily be checked for accuracy at any time: You need a standard index card. The lines on those cards are exactly 1/4" apart. Just sew a few stitches along one line then, using your needle placement feature (I'm assuming you have one) to move the needle one "click" to the right or left and you should have a very nice scant 1/4" seam.
