I have finally achieved the ever elusive scant 1/4 seam and thought that I would share this information with other Bernina owners. I use the #57 1/4 foot. Move the needle to the right 2 positions to the #4 setting for the needle. I also put a piece Qtools sewing edge that I got at Alicia's Attic on the sewing table before the foot to keep the fabric lined up. You can also use a stack of post it notes. I then used a fine tipped permanent marker and made a line down both sides of this guide strip that way I will be able to see if it has shifted and can readjust it if needed. I hope everyone finds this helpful for them.
Happy Quilting,
Robyn
