There actually is a book called "I love to sew with my feet". I found this link to used books. I have had mine for several years....each machine varies, but hopefully this could help you.

Check Nancy Zieman’s blog for Fancy Footwork. There are three episodes that are very helpful. I can’t add link to site with my IPad. —Sandy
Bernina has tutorials for all of their feet on their site. Husqvarna has a catalogue with instructions for all their feet and other accessories. Maybe one of those might help you if your brand of machine does not have instructions.
I would try to Google a YouTube video with the name of the foot...then you would have a video demo to follow...
