Cargo pants bag

At the Maker Faire swap over a year ago, I picked up a pair of boys cargo shorts with the idea of turning the pockets into a bag. Well I finally got around to it! I cut off the leg and ripped the hem to get a little extra material. This gave enough space to do a gusseted bottom. I lined it with red cotton duck, which is pretty stiff and helps keep the shape. The heavy duty zipper and belt/strap are both from the East Bay Depot for Creative Reuse (one zipper down, 231 to go). I've never made a bag like this before and I learned a lot about what not to do. For example, I sewed in the zipper before attaching the strap = difficult. I may make a tutorial for the second leg; that is, if that one goes significantly more smoothly.
