Cute, cute, cute. Think your FIL will go for the pink? lol. Usually when I bind anything, I start in the middle of a side, rather than at a corner. It seems to make the finish easier. Don't know if that will help you but, there's my 2¢.
Also, as 4EVERquilt said, Missouri Star Quilt Company has a ton of "How-to" videos. Check them out. Thanks for sharing.
