A Few Words About Collage
Collage is a medium that can create some very unique creations. It's kind of the melting pot art form. Regardless of how you came to get to the pieces you've assembled, the pieces find themselves on a new plane, as citizens of a new kind of imagery. Your pieces may have been a photograph in a magazine, or a drawing in some scientific publication; they may have been torn from their home in an unspeakably violent manner, or carefully tabbed and photocopied, their shape surgically removed from its environs by a steady hand; they may have been a scrap, discarded and readied for recycling, or they may have been an important piece of something greater, without whom the something would cease to function as a complete thing. It matters not where or whither of whence they came - they are now part of a collage, and this is the only identity they'll maintain.
You might well reason, and you're right to do so, that it's not always easy for collage bits to get along. As the builder of a collage, it is your responsibility to create a balanced and cohesive habitat for your displaced bits and peices. If your intentions are true, and your goal includes the successful coexistence of even the most meager of pasted scrap materials, then there is no reason your collage should not grow and one day become a full-functioning work of art.
