Does the bobbin cover wiggle when you sew?? If it does then that can't be a good thing. I too tried everything imaginable to obtain that 1/4". I must have tried all the 1/4" feet known to man. Also tried the sticky notes. They would pull loose at the worse time. The problem with the 1/4" feet is that they don't cover all the feed dogs on the newer machines which makes it hard for the machine to pull the fabric through evenly. Especially if you're sewing over some bulk. That's when the fabric really goes wonky. I agree that you could try lessening the pressure on the foot. I have a seam guide that came with my machine so I use that and it's worked the best. I do have to remove it when I need to change the bobbin but I butt the seam guide right up against the foot so there's no re-measuring. I just make a note of where my needle position should be. Hope this helps.
