What if you started in the plant graffiti …?
For this you need:
A yogurt, or vegetable milk, both will do the trick, provided they are not flavored.
Two glasses of water or beer.
Half a tablespoon of sugar
Take Plant moss (the garden will go perfectly or you can buy it on the Internet, yes yes; Amazon link)) Rinse and remove the maximum amount of soil and keep only the roots.
In your mixer add all the ingredients, mix. You get a cash!
Take your paintbrush and have fun on a wall! Personally I asked my children and my nephew to write their initials! And that’s the result!
A little patience, the moss can take time to push;-) take care to choose a little bright place
