Cardboard

 Cardboard is something people don't think twice about but think of all its uses. You could make so much out of them they also make good campfires and large fires. They also work good as fire starter But what could you build with cardboard well if you glued them strong enough together you could make a pencil holder. You could also make realistic looking sets for cheap if you paint them right you can make a design then glue it to a wooden shield. You could also make little knick knacks with it then burn whats less also make side tables with if you use stiff cardboard.
