I also just made myself a new bag. This is my Medium Sized messenger bag. It's smaller than the bigger Diaper bag that I make, but it can still fit a standard file folder and all of my essentials (water bottle, cell phone, lip balm, day planner, book, and an extra pair of socks (you never know when you might need those!)). I found this awesome fabric and knew I had to have it. It is distributed by Alexander Henry and it is a home decor weight; feels a bit like a lightweight canvas. And Mom, if you're reading this, your two bags are all cut out (finally) and ready to be sewn. I haven't forgotten!
