I could never get my head around which way to flip the ends to finish off the binding (I always ended up with a twist) until I got the Fons and Porter binding tool. I just followed the instructions and never messed up a single one. It looks so easy now, but I still use it every time. Here is one place to get one and you can see what one looks like (Joann's also has them and you can use a coupon):
