I, too, found that if I am more careful when sewing the corner on, it miters better when I get to the hand sewing. I used to stop at 1/4 inch, now I make sure to stop according to the seam allowance I am using on that particular binding. Bearisgray is so right.....1/8 inch matters! And I err on the side of a stitch too short, NEVER go past the allowance.
