For example 2 of my projects in art 2 didn't use art supplies. The first one was a portrait of Sands made entirely out of red solo cups. The other one was a zonkey made with concrete, sticks, and cardboard.
Why have a boring dinosaur when you can make one out of balloons?
Or Mona Lisa out of peanut butter and jelly?
Maybe Ice Cube made out of Ice Cubes?
All in all I think its better to take risks and be creative with unconventional art supplies rather than being a boring art student stuck using paint and other fine art supplies.
