Have you seen moss graffiti? I’m obsessed. I wish we had a good fence to do it on. It would be a gorgeous and environmental way to do guerilla art. The great part is all you have to do is mix yogurt, buttermilk, sugar, and live moss in a blender and then paint it on. You can water it with a sprayer or just let it do it’s thing. Can you imagine the beautiful designs you could make? It would be so pretty on a fence, old building, or at a wedding. Seen here.
