Part of the first Waldorf Teacher Training. When a child draws an object of nature, a tree, or a rock, for example, he is experiencing nature itself. If he uses solid, unbroken lines to represent the object, he is fixing his perception on something which isn’t really there. In reality, we perceive visual images as gradations of shade and color, never as the distinct outlines we commonly use to draw with. The techniques given in these two lessons allow a child to have a different and truer relationship to his physical world.
