I sew my bindings on exactly as Sewingpup does using my Pfaff Quilt Expression 4.2. Love that serpentine stitch. Had it on my first Pfaff (1472) and programmed it into the 4,2.. I also use it to quilt on top of the seam lines. Not quite stitch in the ditch but close. It reinforces the seam. Most of my quilts are for donation to children and will be machine washed and dried so I want them to be sturdy.
