If there is any HOPE of getting a quilt finished, I have to bind it by machine. I found this neat tool at a shop in Delaware when traveling. It makes very sharp looking corners.
"Quick Easy Mitred-Binding Tool" by Sew Biz. The website is www.sewbizmarion.com - it is larger and easier to use than the binding tool our local quilt shop was selling. (The instructions were easier to understand also.)
