Bruno Munari: Drawing a Tree

For Drawing a Tree, Bruno Munari proposes: "When drawing a tree, always remember that every branch is more slender than the one that came before. Also note that the trunk splits into two branches, then those branches split in two, then those in two, and so on, and so on, until you have a full tree, be it straight, squiggly, curved up, curved down, or bent sideways by the wind."
