Forts, like balls and boxes, never seem to go out of style with kids. We recently purchased a new bunk bed and it came with some excellent L shaped strips of cardboard that are very sturdy. I saw them and thought of marble run fun. The kids saw them and thought fort supports. Fun times!
Viva's newest fort. Tee-pee style!
Bentley's newest fort - he used the sticks as horizontal supports to better stabilize the pillows and blankets. :)
