I do my quilts by machine - sew to front, turn to back and SITD from the front. Invisible from the front and just a nice line of stitching on the edge of the binding on the back. No pins and just a little glue for the corners. My next project is a curved binding on a Spicy Spiral - I'm not looking forward to doing those almost pointed ends. Of course, it will have to be done by hand. If my hands won't let me, I have a daughter who does very nice work, but I'd rather do it myself.
