This is my attempt of making 3 forest terrain pieces for Saga which have to be 1´ square.
This is how I scratchbuilt them:
First cut some MDF tiles and branches and glue them together.
Then put some sand on the bases and cover all with brown paint.
Wash and drybrush the trees...
...and then cover the ground with static grass, tufts, cork and flock.
Glue a styrofoam board on top and cover it in polyurethane foam.
Paint it green, cover the wet paint in herbs and paint it again after drying. Then drybrush and wash it to add contrast.
And there you are: Sherwood Forest, Ardennes, Endor or wherever a forest is needed on a gaming table.
