The term collage derives from the French term papiers collés (or découpage), used to describe techniques of pasting paper cut-outs onto various surfaces. It was first used as an artists’ technique in the early twentieth century.
Collage can also include other media such as painting and drawing, and contain three-dimensional elements.
Collage allows the opening up of conscious, which is very direct…its also a way of looking at what you are consuming all the time – John Stezaker
