Moving onto the base now and here I've used a small Ikea picture frame which has had the edges lined with plastic card and then some polystyrene added for the base of the groundwork. I've come up with the idea of displaying the model on a perimeter patrol and am using the mesh fence from an MMK set.
As I wanted to use the supplied posts for another project I made up a couple of new ones using square plastic rod. The set provides the mesh, posts and barbed wire to top the posts. With the model in place it looks very good I think.
