Target has little pouches that work in the Cube, they are in the automotive area and are "only" like five dollars. They also come in several different colors.
They have a bendable metal piece on the back that I bent into a circle to go around the accessory hook. Though I suppose one could remove that metal piece and cut a slot in the back for the hook to go through.
And NO, I don't work for Target, I know I keep mentioning that store but they just built a great big one near my house. lol
