I also use a 1/4" foot for sewing quilting projects. It's great! Congratulations on your find.
When I first bought my 1/4" foot I just took it for granted -- 1/4" foot = 1/4 seams, right!Not so -- I found I actually had to move my needle to actually end up with a 1/4" seam. Since then, the foot and I have learned to work well together but I do wish it was a little more accurate without the needle move.
I just got mine and love it. It is great.
