I sew mine on from the back first, flip the binding over to the front and then zigzag it along the edge......I make my own binding too, the ready made gets expensive if you do a lot (I do for LINUS). I do miter corners, the way Elenor Burns shows you; that works just fine. I have also seen some quilters who make ROUND corners instead of square corners and they look fine too.Just use a saucer or whatever for a nice round corner on all 4 sides.
