Many lines for a leaf

To stay on the theme of Autumn, we drew leaves using the subject of the lines. In sixth grade classes, we have made the drawing of a large leaf in pencil, and we split it into many parts, drawing the ribs inside the leaf. The ribs were have been decorated with colored felt tip pens, with a series of curved and parallel lines. We created so an effect of fullness on the surface of our leaf. Around the central leaf we drew other parts of leaves, which “emerge” from the frame of the drawing.
For this activity, which lasts about an hour, we need:

drawing sheet
pencil
colored felt tip pens
