Lines can depict any shape; they can create tridimensional effects and give the perception of movement. I did this drawing with 6th grade students, in order to create a mountain landscape using just lines. Putting lines near each other, you can create the perception of threedimensional volume and our eyes see undulations, protuberances and hillside indentations.
We started the drawing with the main lines of the mountains, the sun and clouds in the sky. Starting from the shape of these edges, we put the lines near each other, following the direction of the main lines. We have drawn the image with felt-tip pensrati.
