Thanks for the idea ! I have a distance bar for my Bernina, but it will only work with a certain foot. That foot does not allow me to use the dual feed attachment. Using the dual feed attachment is like using a walking foot. So....I want to use my walking foot (dual feed) to straight line quilt, but can't use the distance bar to keep my lines equidistant. Someone please make that make sense....So now I will try the blue painter's tape to hold that distance bar in place.
