Dolphyngyrl is correct if a 1/4" foot came with your machine. I had to purchase a shank to use it with my older Bernina. It was the first 1/4" foot produced for sewing machines. When Bernina finally came out with a quarter inch foot years later, I bought TWO of them for both of my Berninas. The little foot does have a side with an 1/8" guide but I have never found that I needed it. I also ooccasionally use her big foot for free motion quilting!!
