Artists often borrow images from many sources and put them together in new ways. You may want to try this at home—clip some pictures from old magazines, photographs, or newspapers that you might otherwise throw away. You can also use construction paper, colored tissue paper, wrapping paper, old greeting cards, labels, stickers, and other printed materials. Place these cutouts on a sheet of heavy paper or cardboard, allowing the surfaces to overlap. Once you have arranged the pieces the way you like them, glue or paste them to the background. If you like, you also can paint or draw on the surface to add a handmade quality to your work.
