Hey, Cathe. I'm betting you do just fine with your system. If you are in the market, though, for a quarter-incher that covers both dogs, the Brother foot i showed the link to is shaped in a way that provides a nifty quarter inch reference, but is wide enough to feed using both dogs.. Take a look. (nope. i promise. they aren't paying me to sell this foot. the one i've tested belongs to a friend of mine. :lol: )
