I came across moss graffiti on the Heavy Petal blog and I love this idea of creating images made of moss. The recipe is simple and I am going to have a go myself as soon as I can. This is what you do:
1 can of beer
1/2 teaspoon sugar
Several clumps garden moss
You will also need a plastic container (with lid),
a blender and a paintbrush
To begin the recipe, first of all
gather together several clumps of moss (moss can usually be found in
moist, shady places) and crumble them into a blender. Then add the beer
and sugar and blend just long enough to create a smooth, creamy consistency.
Now pour the mixture into a plastic container.
Find a suitable damp and shady wall on to which you can apply your moss milkshake. Paint your chosen design onto the wall (either free-hand or using a stencil). If possible try to return to the area over the following weeks to ensure that the mixture is kept moist. Soon the bits of blended moss should begin to recouperate into a whole rooted plant – maintaining your chosen design before eventually colonising the whole area.
