I watched "Sew it All" this weekend on PBS and she showed a way of binding that I didn't know about. I wish I could find a video but I did find the episode:

Basically you prep the end before you start by folding it over 1/2", and instead of sewing the ends together - after you've attached the binding all the way around - and hoping you get the length right, you just tuck the folded end inside. It didn't even look like she sewed that seam together.
