I use the Martelli binding system. Sew the binding to the front, flip it to the back, use the binding tool and the STID foot to stitch from the front ditch. Works like a charm. I get very even binding that looks nice on the front and the back and is very secure for quilts that will be washed etc. I don't know that it would pass muster for a competition, but for bed quilts, lap quilts, home dec wall hangings, I think it looks very nice.
Is there a tutorial out there on the method someone mentioned about putting the binding on from the back and then using your machine's decorative stitches to sew it on the front? That sounds interesting. How does it look on the back?
