If you have unfinished walls in your garage, you can make use of the space between the studs. For example, using scrap wood or some 2x4s, you can build a clever ball storage solution. Attach two three-sided wood frames between two wall studs; put one at the base and the other about four feet higher. Drill one hole on each side piece of wood and two holes on the front pieces. Hook bungee cords through the holes, and you'll be able to keep your kids' playthings in order.
