I do mine by machine. Sew to front, fold to back, stitch in the ditch from the front. If I can't find where I started when I get back there, then I don't see the reason to hand sew unless the quilt is handsewn. This may get me in trouble - nothing new about that, but I do not care for zigzagged binding. It just doesn't look finished. I'd like to try a blindstitch if my machine's blindstitch went in the right direction, but it doesn't.
