I needed a large chamber for the Under Wittenberg game. I decided to use a box folder and make it as adaptable as possible.
I removed one side of the box folder to make photography easier during games. I cut some coffee stirrers to size and fixed them near the corners to provide a groove at each end to fit swappable wall effect pieces.
The cardboard inserts for the wall sides cut, covered in stone paper and checked for a good fit
Onto flooring - some pavement effect paper sheet, cut to fit (future option of swap out floor piece)
A little bit of dressing to check on how pictures would look..
