It was hard to get a good photo of this, this is what is now hanging on one of our walls. I found an old picture we had for our kitchen in our last home (we had a few of these and I used one of the other ones for my Subway Art.)
This is the before:
I simply sprayed it black and wrapped some twine around the wood in a random pattern. And that's it! Its pretty simple but I love the result. I also love how easy this display makes it to change pictures out. For some reason, I'm really bad about changing pictures once they are framed.
