This is how you make a real collage. Be very careful with the scissors and check first to make sure the pictures you plan to use in your art aren't too special to be cut up for this project.
Cut out pictures, patterns, or shapes, then arrange them on a sheet of cardboard or heavy paper. Make interesting combinations by overlapping or rotating your collage snippets. When you have everything in the perfect spot, carefully paste each picture to the backing. Once your collage is dry, you can decorate it with markers, crayons, or pencils.
