gigi712, I feel your pain. I'm new at piecing and self taught and have a Janome 6500. I've spent I don't know how much on quarter inch feet. I kept thinking one would work better than the other. They're fine when just piecing two pieces of fabric together. But........ when there's bulk in the seam you're sewing, the fabric skids out of control because the 1/4" foot doesn't cover all the feed dogs. So, what works for me now is using the seam guide that came with the machine, using a full size regular foot that covers all the feed dogs and moving the needle to where I need it to be. If you have an accufeed foot with a 1/4" guide, that should work good for you. Good luck!
