I have a Brother Innovis D 4000. I use a center needle straight stitch, changing my stitch width to 2.5 and using the inside right edge of my "J" foot as a guide for the edge of my fabric to achieve my scant 1/4 inch seam. I have several of the 1/4 inch feet and don't like them because of the dragging on any fabric they catch on. I can not use the 1/4" seam guide on my machine. It's too far from the needle and I can't seem to stay straight when my material is right at the end of a seam.
I would think it would be very difficult to sew with the fabric only being pulled by one of the feed dogs. You would always be trying to keep it straight.
It all comes down to what works for you. I am working on Judy Niemeyer's Bali Wedding Star. This is my first paper pieced project. It has really helped me work on my 1/4 inch seam having those lines to aim for. I wish I had realized this a long time ago. My sewing would have been much closer to a 1/4 inch seam a lot sooner.
