Collage is an art technique that has been around for hundreds of years.  In the 20th century, it was a popular technique used by Picasso, Georges Braque and Matisse.  I am fascinated by the process of taking bits and pieces of this and that and putting them together into a piece of art.  The only problem is my fascination with this process means I can hardly throw anything away because I always envision a use for it in the future.
