My Bernina walking foot quit on me! :(
I thought that I may have bent it or wasn't attaching it properly - needles kept breaking - so I took it to my LQS and the dealer tested it and found that it wasn't engaging - she said that it may have just worn out! I didn't want to order another but had no choice since I was in the middle of a project and had to get it done. It was old but I didn't know that they could break or wear out.
Has anyone ever had this happen to them? Do you know if they are fixable?
