I use my quarter inch foot and place the metal guide on the drawn line, sew and then do the other side. usually i sew just inside that, meaning i place the foot just "inside/off" the drawn line. then press and trim if necessary. if you trim always place your 45 degree line on your ruler on the seam you sewed.
