Why cardboard? The cardboard story started during my studies at the faculty of arts. All the assignments, if possible, were made of cardboard. For my final project I choose white piece of cardboard (1:1) presenting a piece of a street (for more information and photos please go to my blog - "nie użytkowe"). There are many interesting properties of cardboard, starting with solid cardboard which has got layers of cellulose, which can be ripped off or cut so that is flexible.
