As my 1/72 collection grows, so should the number of matching terrain pieces. These are my latest inventions: swamps made from coasters, a blue foam hill and a coir door mat cut up to represent wheat fields and such.
The hill is made from two layers of foam and there are two pieces of bark added. One side is impassable for troops.
The swamps are made from fish tank foliage - the pools' surface is PVA mixed with dark green paint. The coasters are made from paper, so they bend a little.
