I've been working on ways to cover my shelves and make my room look more unified, all without spending too much money. Here's how I've been doing this: Take black butcher paper and cut to desired size. Put a cute picture from a calendar in the middle (Dollar Store calendars rock) Put a border at the bottom. Laminate the whole shebang. Attach with a strip of color-coordinated duct tape to the shelf above. If you're working with a very wide shelf, it might be a good idea to make separate "doors" that are half or 1/3 of the width of the shelf. That way, you don't need to lift a long, heavy flap. Just lift the little door you want to move. As an added bonus, you can say, "Hey, Joey, go get a dictionary. They're behind the tiger!"
