Thanks everyone for all the comments! I'll be making a run to the Dollar Tree to pick up 3 more frames so I can add a 3rd row. Thanks for all the tips and advice. 

I wanted to share how I hung up the photos I used Command removable hooks to hang up the photos because we have plaster walls and I'm always afraid I'll make a big mess of it when hammering in nails! 

Kris - love your idea to use newspaper! I'll have to try that with my next crazy photo wall project!

Michele - Thanks for the encouragement. I'm planning on finishing up most of the Spring Cleaning this weekend!
