For the first time I attempted to utilize cork bark to make some modular hills with rock faces. I also used the natural shape of one piece of cork bark to make a cave piece.
These were taken in progress, I have since flocked these and they look much better with green added, but you get the idea here.
I glued chunks of cork bark in a semi-circle to a piece of mdf board. I then used a chunk of insulation foam to fill out the hill shape behind the cork bark. I then used wall filler/spackle to fill in gaps. I added a layer of sand and gravel over it and then painted it dark brown with drybrushing.
The cork bark itself is painted dark gray with a lighter gray dry brushing followed up by a final dry brushing of pure white.
The cave piece was just an inspiration that I had when I saw a natural hole that was formed in the piece of cork bark I happened to buy. I thought it looked just like a cave and so I made it into one!
I got a pretty decent-sized chunk of cork bark from my local pet store, it was MUCH cheaper than the prices being charged online. This was about $15 USD and was enough to do a couple hill pieces and the cave piece.
