One technique is to sew the binding to the front, carefully fold over and glue the binding to the back so that the edge just covers the stitch line, then stitch from the front in the ditch while the glue holds the binding in the right place. This stitching will just catch the edge of the binding on the back. Another technique is much the same, except that you zigzag the seam allowance with fusible thread, and then instead of using glue you just iron the binding onto the fusible thread, then stitch in the ditch from the front. In either case, your final stitches do show on the back of the quilt, but not on the front, because they're in the ditch. On the back they are supposed to be nice and even because you've used glue or fusible to hold the binding in just the right position. I've tried the glue method and it worked okay, but I still prefer to bind by hand. My friend has used the fusible thread very successfully.
