Just checked my box again and I would say big packing error. Not only do I have a P foot but I have two P2 feet. Now i Wonder if I'm missing any feet that belong to the machine. Have to dig the book out again and check them all. I don't do free motion on it and don't change from the walking foot so never noticed the error. Until I got a long arm (used) a couple months ago I always hand quilted.
