I'm gonna follow this to because I was going through the little box with all the different feet my mom has that my aunt gave her when she gave her her old Bernina 830 and I found a walking foot too. Never used it, think my mom might have, but after 20 minutes of trying to figure out how to get the darn guides on, I finally picked up one of the little papers with the instructions. But it doesn't tell me what I can do with it :( sorry for rambling! Sarah
