I use the 1/4" foot with the flange. I leave a small gap between the fabric and the flange to get a 1/4" seam. It is not perfect, but it is the closest I can get.
fatquarters,
What is the name of the foot you use? I don't really understand your description. Sorry.
Here is my gripe with my 4.0. Fabric dips down in front of the bobbin cover and will flip seams. I cover the dip with tape. Does anyone have a better suggestion?
