I was introduced to the universe of collage in the early days of College, as an exercise of fluid experimentation. The teacher wanted us to expand your minds and lose the sense of perfection when doing things. We had to go with the flow, it was a king of visual brainstorm, in which the concept of the pieces where being built/ form, alongside the collage.
Since then, I’ve been using this technique to practice compositions and concepts that are less strict or defined, and many times introspective. All of these are autoral pieces.
