I am currently doing the diorama base for the Flak 36 model that I am entering into the Towed Gun Group Build in the Armor Forum. The basic idea of the dio is the Flak 36 located in a camouflaged position in front of a church ruins. Right now I am doing the church ruins. Here are some progress pics:
I used foamboard as my basic material together with some styrofoam and popsicle sticks. I'll be doing the roof tiles, stained glass windows, door and other details next.
