We decided to make a "Battle of Kashyyyk" fantasy set.
The first step was to make a draft of a treehouse on my chalkboard.
We had so many brown pieces, it was easy to build. We used string to stabilize the structure. We had to drill into a few bricks to stick axles through them. That was fun.
This photo shows our project in front of two treehouses that we made about two years ago.
