What you will need is a box, duct tape, and spray paint.
Spray paint your box any color you like and use the duct tape around the top to finish it off. You can either cut the top tabs off or bend them in and tape them down to provide more strength. Very easy project for pennies on the dollar. I needed a box for my kids lego's and this cardboard box was a perfect size for their entertainment center so I decided to make it work. We used black spray paint with a hammer finish and white duct tape to match the curtains I made them. I think it turned out pretty good :)
