I have the 1475cd, and I have done FMQ on it with success. The Pfaff has IDT, the 'built in walking foot', so no need to buy one. Yes, I use the darning foot. My machine has a setting for darning (or fmq) in the foot lift...it is not raised all the way up as for normal release when sewing, but rather you raise and nudge it to the left about half way up. You do not drop the foot all the way down as if to sew a seam. This sets the tensions so the threads lock. Drop the feed dogs and away you go.
