I finally figured out that the 1/4 inch foot does not maintain a 1/4 inch. It's always too big or not consistant. I move my needle to the right (on my Elna, it's to 6.5) and use the edge of my foot as a guide, being careful not to look at the needle, but keep my eye on the edge of the foot. I know it's a pain to always have to move the needle when I first turn on my machine, but so rewarding.
