On my Bernina 1230, I move my needle one notch to the right to get my scant 1/4" seam. I have never been able to get accurate seams using a foot. I measure my 1/4" from the needle, then place a physical barrier so I can butt my pieces against it when sewing. I can sew much faster with this barrier. Have cut up and used moleskin in the past, but now I use a Dritz adhesive seam refill because it is higher. (Do not trust their red "seam gauge" that goes with these refills for setting your 1/4" seam. I measured it, and it is set for a full 1/4". If you use it, your seams are almost guaranteed to be a little too big.) I would have posted a picture, but no one on Amazon seems to sell it right now. Got my last batch at JoAnn's for under $3.
