Moss graffiti is eco-friendly as it doesn’t use any aerosols; what the “painting” needs is just a dash of water to thrive. Here is a recipe for how to make your own moss graffiti.
To get started you’ll need:
3 cups of moss (washed, clean of soil)
2 cups of buttermilk or 2 cups of yogurt (should be plain yogurt)
2 cups of water or beer
1/2 tsp of sugar
corn syrup (optional)
