We have tons of family photos that I would love to display when our house is renovated, and I have a couple of ways I'm thinking of doing it. This first one is my idea for the playroom--large, simply matted photos of each of the three kids. I like how clean and fresh this looks.
The second idea is to have a gallery wall, possibly in the hallway, using photos, the kids' artwork, and other special/sentimental things. I've never quite known how to put one together, but this one is inspiring me (DIY instructions here).
