How long should a walking food last?
I think I broke the second one I bought. I tested it with just fabric and it seems to sew just fine, but when I try to quilt with it it messes up. It started doing this all of a sudden in the middle of a quilting project. I really haven't had it very long. What am I doing wrong? I have already tried cleaning the lint out of the machine, rethreading, reinstalling the part and changing the needle.
