In the end, I decided to hang it on the door to the boys' room. And I love it! The sentiment is so over-arching, I love the idea that it is what greets you first when you walk towards the boys room. And as I head up the stairs or down the hall, it makes me smile.
I love the idea of extending your wallspace by using bedroom doors. And no need to worry about nail-holes. I used these Command picture hanging strips and they worked great!
Do you hang art in any unexpected places? Tell me about it! I'd love to hear your good ideas!
