Started making some trees yesterday and got some assistance from my little buddy Ben!
Using some Poly Fil fiber, hair spray, flat black spray paint, various dried floral material, and a special blend of ground foam material we built over 25 trees in just about 2 hours time.
Method 1 ~ Poly Fil, dry floral material, floral tape, flat black spray paint, hair spray, and ground foam material.
Coat some hair spray onto the armature and then stick the Poly Fil on

Then spray on some flat black spray paint

Then apply some hair spray and coat with some ground foam material

Method 2 ~ Dried floral material, hair spray, ground foam material.
Cut the specified dry floral material

Coat with some hair spray

Then roll in the ground foam mix

Shake excess and hang to dry

Some dry on the foam sheet too

And the forest starts to grow (needs more fertilizer)

Twenty-five down......five thousand to go!
