Sorry I read your question wrong and did not answer correctly. However, the 97 foot is the best foot I have.....I use it for a lot of things. Not sure if your machine is compatible with this foot, but since I started using it I do not have trouble with the 1/4" seam. This foot works in conjunction with your feed dogs.
Did you know you can down load an app for Bernina Feet? You download it to your phone or ipad free. Hope this helps.
