These would make an awesome staircase to an attic. I would love to see some Harry Potter books on there. This would also be cool with movie titles on it as well. I love this staircase--- more folks should do stuff like this.
Every time you visit a new place, pick up old or unused license plates. Attach them to a staircase at home. This is a unique idea which will light up your home with your travels at every step. Get creative and add fairy lights for flair!
