I am wanting to try FMQ now that I have a walking foot. I don't know where my instruction manual is for my machine. I am making a wild guess here but is the feed dog the little teeth looking thing that comes up thru the plate, if it is then how do I drop them so that I can FMQ. This probably sounds real stupid but would someone tell me if I am right and how to drop them. I have had this amchine for a couple of years and I am still learning things about it. It is a brother LS-30 if that helps.
