Moss Graffiti is where it's at!!! <3 Oh my word!!!! How cool is this?!?! I am a huge fan of moss (or really anything that's green and grows up the side of walls) annnnddd interior brick design. I would totally take this idea indoors, and grow my moss graffitti on my favorite (non-direct-sunlit) wall! What an awesome idea! The "recipe" is included in the blog post.
