I don't know if this information is helpful, but my friend has a Pfaff with the IDF and she took it to the dealer and was told that there was no FMQ foot for that particular machine and that she wouldn't be able to do FMQ on it. I know it is an older Pfaff. She is coming here to practice on one of my machines to see if she likes the idea of it, but will have to borrow one of mine or get a new one.
