On my Pfaff, I have used the wide rubber band - but recently I switched to the screw on seam guide (optional), setting it so it is right against the presser foot when lowered, and when ready to sew, move the needle 3 positions over (until you get the 1/4" measure) - and it came out perfect - - - the fabric can't go anywhere because it is literally sandwiched under the presser foot and against the seam guide.
