All my Mutiny stuff is individually based on 2p coins. Very simple, I glue the figure in the middle with super glue and then I just cover the integral base and the coin with ready mixed wall filler. I paint them with craft paints. A medium brown called earth for the base coat which I water down so that it spreads on the dry filler. Then just drybrushed, heavily, with a beige and a sand colour. Add a few silfor tufts or static grass and thats it.
