A collage made up of two or three elements only is, in many ways, my platonic ideal of a collage. With so few pieces, each has a lot of work to do. There's no room for wasted scraps, careless placements, or purely random "stuff". You're not relying on complexity to create interest. You're working without a net.
When a collage this simple clicks, to me at least, it starts to sing. It's simplicity lets you see everything that you need to see, and invites you inside - and much to your surprise, there is an "inside".
Mixed Media Collage: Found paper, watercolor wash.
Note: Collage is sold matted but not framed.
The matted collage measures A4 280mm x 350mm, which is a standard frame size. Pictured frame is from Modular.de.
