Only a few hours left to Double your gift

Do you have a blender, a bucket, some buttermilk, and a strange compulsion to beautify your local walls without using harmful spray paints? Do you also know what “water retention gardening gel” is? (I don’t.) Well then you, my friend, have the ingredients for moss graffiti, and in just eight steps you could be doing gorgeous art like this.

I’ve had a hard time finding a source to credit for the instructions infographic, which is old but has been going around the internet again, so if you know where it’s from originally, please let me know. Preferably by writing it on a wall in living moss.
