Watch the video where I demonstrate how to draw light and dark ovals of different sizes as relaxed as possible.
Recording: De Foto Firma
Exercise 1: Try to imitate the exercise from the video. Move your arm as relaxed as possible, without bending your wrist or squeezing your pencil. Start the movement in the air before you hit the paper. Let your hand gently glide over the paper while drawing. Try it both clockwise and and counterclockwise.
Exercise 2: In the same way try to draw long straight and wavy lines, circles, ovals and large scratches, light like spider threads as well as dark (image).
