I made two of these for the kids and they use them all the time. I chose light canvas for the outside because I knew I wouldn't be able to handle it if I picked out some wonderful fabric only to see it dragged across the parking lot or filled with rocks. I used the fun fabric on the inside. And somewhere on this computer I think I have pictures of that but who knows where. I also added a little elastic hair band to the inside seem to hold their kids thermos. It fits perfectly in there and stays upright. I'd show a picture but ... Oh, and even though this is a very small thing, because the bag is a mucky canvas color, I added a bit of flair by using hot pink hardware on the strap.
