Here are some images of bases I made ling ago for some terminators (pics coming tomorrow) using some very simple materials.
Nothing terribly fancy. Just some cork, some bits, some glue, some grass, and some paint. I have made some bases that are so incredibly complex, I forget at times that even very basic stuff like this can be effective.
I guess I am after very specific themes with my bases, trying to set a story for every army. Obviously, these are quite generic, all purpose stuff.
Still, basic can still be purty! :-)
