This is the manufacturer of the feet. It looks like they have both high & low shank feet made for DSM's as well as templates to work with the thickness of the feet. Rulers made for long arms are too thick to use with these feet. I watched several YouTube videos put out by the company including one for the foot for my machine. It looks like something I'd be interested in. I am anxious to contact the store that carries them in my area to check them out.
