Someone made me a bag just like that - and I love it. I have pockets on the inside. I never looked under the flap to see if there was a pocket too ... nope, mine are on the inside. I bet she folded it a little wrong. I use it to hold some crochet hooks, my scissors and some fluff for stuffing my dolls when I make them.
Here is the tutorial that the person who made it for me used. It's an origami bag.
