I bought these keys from a website called
Pick Your Plum. They have one really awesome deal every day. It took me a few weeks to decide what to do with them.
I gathered up all the odd photo frames we had in boxes that I was trying to decide what to do with. My kitchen and great room are decorated with green so I spray painted the frames green and also did a few in yellow and gray just to add a little variety to the room.
I positioned all the frames where I wanted them then used some tiny nails to nail the keys in place.
It turned out something like this!

I loved the texture and rivets that a few of the empty frames had. I made a stencil and spray painted a Pp in this one.

Still deciding what to do in this one. Any suggestions?

One of my favorite frames is the Party of 3 :) I used my Silhouette machine and cut some vinyl for that frame. I got the idea from Shelly of
House of Smiths - She is pretty much a decorating genius!
This wall adds so much personality to the room. I'm hoping to find a really great chair or old cabinet to repaint and put below the collage.
I can't wait until Addison is older and we tell her those keys are our spares for the burried treasure chest, our stage coach, and our gringott's vault ;)
