The only foot I use for FMQ is the darning foot. (round, clear beast that has a spring in back; some are open toed). I have FMQ'd using a regular foot (but clear) as well. I still drop the dogs, but that's my preference. As far as a stitch regulator goes-it is an unnecessary expense for me. I used to have one, but it got lost, and I haven't missed it nor replaced it. Some swear by them, but I just put my lips together and blow. :lol:
