I just recently heard of moss graffiti, and lets just say my mind is blown. It is one of the neatest things I have, or ever will see.

What's the coolest part about moss graffiti? How easy it is to do!! You need a blender, and I don't have one or I would have made SO MUCH already and posted a DIY. But This website has nice instructions on how to do it yourself!
