Tree foliage for diorama can be made by lichens moss and sponge,This is my method that I’ve find do foliage by myself because I can’t find a dealers near my home for this article , and order by internet became expensive for few pieces.
what you need:
old blender
sponge possibly green
acrylic colour (I’ve used green apple)
little tank
water
brush
- put your sponge into blender and begin to cut
the result will be more fine and more bigger continue since when you have a good size for your tree
2)put your colour into little tank with water
3)add milkshakesponge at tank and with one brush push on it
after all the resulst will be like this
now put your foliage to dry
and after you can pout on tree
