This is perfect for spraying over open areas, or to fill in between clumps of existing moss, and of course to paint onto rocks, logs, etcetera.
One half cup moss, crumbled into bits (fresh or dried)
One to one and half cups water (lukewarm)
One quarter cup buttermilk or beer
Place in blender and blend for approximately two minutes, creating thick slurry. Add additional moss bits if not thick enough.
