I am one of those people who every time we go out I throw a couple of snacks for Riley into my handbag. If he doesn't eat them they get forgotten about and the next time we go out I throw in some more. You get the picture, after a while I have heaps of food floating around in the bottom of my bag. So for me a snack bag was the perfect idea to keep all his snacks together and it makes them easier to find (my bag can be a bottomless pit sometimes). Before I go out I can check it and add to it if I need to. It was really quick to sew (using this tutorial here) and has a velcro closure so its easy for Riley to help himself.
If I was to make another one, the only thing I would do differently would be to box the corners and make it a bit bigger.
