I agree who ever dreamed up this scant 1/4 inch thing had nothing else to do I have never used it and my points have always matched years ago when Mary Ellen Hopkins was a very famous quilter with her book {it is ok to sit on my quilt} in her classes she taught the ppm measurements which is personal private measurment and she said consistance was more important that the seam allowance so I learned her way first then did learn to manage the quarter inch which is good enough for me after all quilting is suppose to be fun enjoy
