Here is one for you guys.
I needed a tropical/overgrown scenery for a WFB game. Soooooooo here is a simple way to do it.
Start with a sheet of MDF board (its great because it doesnt warp easily)
Cut to desired shape and size. Then flock. I use 3M glue in the spraycan. It holds flock on a surface like nobody's business. I drove nails through the backside (I'll explain later)
Next cut up little points from plastic sprues which come with GW plant set and glue in place. Clear a little flock off so you can glue directly to wood surface.
Next glue the lichen in. Use a good amount of glue on the base so the stuff sticks and doesnt fall off later.
If you want it to be impassible or very dense, then add more lichen.
Cut up those GW plants to desired shape and size. I also used aquarium plastic plants, the varient is awesome for some of those more exotic looking plants. They look great and you get alot more for alot cheaper than the GW stuff. (isnt that always the case)
Begin gluing the plastic plants to those little pointy plastic pieces. They are there to anchor the plants in a little better.
Then add your trees. Remember those nails I drove through the back of the wood. Well, what do you think is holding the Trees in place. Those are home made trees. They are made out of bambo sticks, foliage clumps and LOTS of glue.
Then take a spray bottle and use a 50/50 mix of good old Elmers glue and water. Spray the entire piece heavily with mixture and let dry over night. The glue will dry and do three things for you.
1) Take away some of that glossy plastic look from your plants.
2) It will also give a little bit of a weathered look.
3) It will give a final layer of glue to hold everything together.
There you go. I did 10 of these bases in one weekend. Hope this helps somebody in the future.
