Here is a look at a small tower that could go into the cardboard castle. With this little project I was just experimenting with details. Everything here is cardboard. Even the shingles and edging are from the top layer of paper in cardboard (Kraft paper). Corrugations also make for some interesting details.

The overall design and structure of the castle is important. The design of each building is important. And.... the detail work on each building and structure is also important. Take a look. Leave a comment and let me know what you think.
