Knock off Ideas

I want to make a bag similar to this one:

I have made a few box bags so I know how to make the middle section. I can't quite figure out the best way to attach the two side pockets to the middle section. Any input/ideas about how to make it would be greatly appreciated.

My guess would be to start from the middle of the bag out. Make the boxy middle w/a long outside piece & sew on the other side to make it into a pocket & repeat on the other side. That would take some doing, good luck. Show some pics when you get it done.

Thanks for the advice.  I hope that I can figure this out. I must have this bag.
