I have found that the 1/4" foot sometimes makes your seams a little bit bigger than 1/4". I usually use a regular foot that accommodates zig zag stitches and move my needle to the right until I get a scant 1/4". On my Elna and Brother the needle position is 6.5. Also by doing this you have more of the presser foot on the fabric, which keeps the fabric from wandering. Happy quilting.
