I made a backpack last weekend using this tutorial: http://sewmamasew.com/blog2/2010/08/back-to-school-free-let%e2%80%99s-go-backpack-pattern-tutorial/

I liked the pattern so much, that I decided to use it again for my little girl's diaper bag (I'm due in December).  


                                    

I added the envelope pocket, 2 magnetic snaps, thicker interfacing, and a different way to make the straps.

I have more pictures on my blog: http://ourminiatureadventures.blogspot.com/2011/07/lilys-diaper-bag.html

Edit:AND I'm planning on writing tutorials for how I changed the backpack from the orginial tutorial @ SewMamaSew.

My tutorials are up on my blog!! http://ourminiatureadventures.blogspot.com/p/my-tutorials.html
