Since I ran out of black and white fabrics, I let Adam choose the fabric for attempt number tres at good old Wal-Mart. He chose a teal, blue and black camouflage fabric with a blue and black starry fabric for the lining. I chose a black zipper to go with it, and got to work.
This is attempt number three. Unlike Goldilocks, I did not strike gold with my third try, but I am closer to my goal. The bag is still too deep, so it doesn't hold the Gameboy as snugly as I would like.
