Have you used this 1/4" foot to make other quilts? And have they fit together ok? I agree with others that what is most important is "consistancy" in your seam width. Do not change the seam width on the middle of the quilt but continue to sew with this same foot. On your next quilt change the foot or make adjustments if you want. Seam width may be a problem if you are sharing /making blocks for others.
