First a dibujo in pencil on a sheet of paper. For example, a cow. Color is given below throughout the dibujo gluing small balls of onion paper on. I paste blue marbles on the sky, green marbles on the grass, black and white marbles on the cow, yellow marbles on the sun, brown and green marbles on this tree here, etc.
To make the balls cut the onion paper into strips (by hand), make the ball, and soak it in a little white glue to stick it.
Material: sheets of paper, pencil, rubber, onion paper of different colors, white glue.
