You can use a regular foot and move the needle over so that you are sewing 1/4 inch from edge of that foot. I have a friend with a Pfaff and she does that even though she has 1/4 inch foot. Says feed dogs get a better grip on fabric that way, more of fabric is actually over the dogs. My machine will not do that as my needle moves are in too large increments. I hope this makes sense.
