I also bought the accufeed 1/4" foot. In order to get a 1/4" seam I had to move my needle to the right at about 5.5, and it was still too big. With the regular 1/4" foot I just move the needle right to 3.8 and I have my scant 1/4" seam. It was also hard to keep the seam straight with the 1/4" accufeed foot. Got it & a stitch in the ditch accufeed foot from Brubakers.
