One or two clumps (about a small handful) of moss
2 cups of buttermilk
You can also substitute with yogurt (vegan yogurt can be used)
2 cups of water (or beer)
1/2 tsp. sugar
Corn syrup (optional)
1 Gather up as much moss as you can find or buy.
2 Wash the moss to get as much soil out of the roots as possible.
3 Break the moss apart into manageable pieces and place in blender.
4 Add the buttermilk/yogurt, water/beer and sugar. Blend the mixture until completely smooth. You’ll want it to have a paint-like texture. If the mixture is at a consistency where you feel it will drip, add corn syrup until the consistency you desire is reached.
5 Use a paintbrush to apply the moss-paint to the surface on which you wish your design to grow.
6 If possible, check back weekly to either spray the design with water (to encourage moss growth, especially if you live in a dry environment) or apply more moss-paint.
