On Jill, the quarter inch foot is way over that measurement. I used it once and it was 3/8" or more when putting the fabric against the flange. I now use the regular foot and the markings on the machine and throat plate and I have consistent 1/4" seams now. The foot, which appears identical in looks, that I use on my old machine, which is a Singer, gives me a perfect 1/4" seam. Matter of fact, that foot is a Babylock foot as Singer did not make one when I was looking!!
