See, this is what happens when your a designer. For other people's homes, its really easy (I find) to make decisions for them. When it comes to our home, I tend to over think things or leave things empty until I find the perfect item for the space. (Because I know it exists, I might just not have found it yet...) So when it came time for the wall art in lil' man's room, I got the best of both worlds.
I used (6) 12x12 frames over his crib (three on top, three on the bottom) and put scrapbook paper inside so I could switch them out as I saw fit. One of my favorite reasons for this is that when we switch out the papers, its a project lil' man and I get to do together.
We shop for the paper together, he points to ones he likes...and I point to ones I like. Then we buy the ones that make most sense.
When we get home and make the paper switch, its always fun for me to watch him lay in his crib and look up at the papers and go, "ooooooh" (Especially at Halloween when we hung super cute paper that had friendly spiders and mummies on it. He LOVED it!)
