For my Upcycle project I will be using primarily cardboard. The aesthetic that I will be going for is a modern car look. I am going to use the cardboard and cut out pieces and try to mimic the look of a body supercar. In the following pictures you can see some examples of some that have already been made.

I think that it will be cool to take something such as cardboard and be able to create a functional model car and the materials that I will be using in this will be cardboard, paint and glue. https://www.youtube.com/watch?v=SqwQ9D5hsYc  https://www.youtube.com/watch?v=4yY4NuJoOuw
