We didn't plan out our pictures first and just took a more creative approach, and started in the middle, and moved towards the ends of the hallway. The really nice thing about not buying additional things to decorate our new space is that all of our belongings are on remix! At our house the color frames were in one room, the black frames in the hallway, and the "Keep Calm and Carry On" canvas was in my office at work; now they all go together and I am really happy about the result. Many of the pictures are from our wedding, trips and travels, and good friends--it makes me really happy to see everything on a daily basis again.
It was kinda hard to shoot the long narrow hallway, but here are my best attempts. Let me know what you think, I love comments :)
