Did the walking foot not fit on the Bernina? Bernina's have several different shank attachments, so not all Bernina feet fit on all Bernina machines. If you want to purchase a generic walking foot, you need to purchase a Bernina shank adapter. This is a little piece that fits the Bernina on one end, and a low shank foot on the other. However, a generic walking foot will probably never work as well as a walking foot made specifically for the model of Bernina you have. Unfortunately, Bernina feet are really pricey -- especially the walking feet.
