DIY Green Graffiti

You'll need:

• 1-2 handfuls of moss
• 2 cups of buttermilk or yogurt
• 2 cups of water (or beer)
• 1/2 tsp. sugar
• Corn syrup (optional)  

• Paintbrush
• Blender

Steps:
1) Wash the moss to get as much soil out of the roots as possible.
2) Break the moss apart into manageable pieces and place in blender.
3) Add the buttermilk/yogurt, water/beer and sugar. Blend the mixture until completely smooth. You'll want it to have a paint-like texture.
Note: If the mixture is at a consistency where you feel it will drip, add corn syrup until the consistency you desire is reached.
4) Use a paintbrush to apply the moss-paint to the surface on which you wish your design to grow.
5) If possible, check back weekly to either spray the design with water (to encourage moss growth) and/or apply more moss-paint.
