We had started with a cardboard mock up and decided to use the cardboard on the rooftops and front and back of the building. To sturdy up the upper walls we'll use luan and an interior support of foamcore. Why luan? Why not. Our reasoning was to make the removable roof sturdy enough to withstand wear and tear. Secondly it has a nice texture already, so no facing will need to be added.
We notched the area where the luan would rest.
Viking Trading Post we built back in May. Using craft sticks, tape several together. Place as many as you feel comfortable working with. We need just over 18" of wall so that's a lot of sticks.
Have a Great Battle,
The Old Crow
