Many origami books begin with a description of basic [[Yoshizawa–Randlett system|origami techniques]] which are used to construct the models. This includes simple diagrams of basic folds like valley and mountain folds, pleats, reverse folds, squash folds, and sinks. There are also standard named bases which are used in a wide variety of models, for instance the bird base is an intermediate stage in the construction of the flapping bird.<ref>{{cite book|title=The Practical Illustrated Encyclopaedia of Origami|author=Rick Beech|year=2009|isbn=978-0-7548-1982-0|publisher=Lorenz Books}}</ref> Additional bases are the preliminary base (square base), fish base, waterbomb base, and the frog base.<ref>{{cite book|title=Origami to Astonish and Amuse|author=Jeremy Shafer|year=2001|isbn=0-312-25404-0|publisher=St. Martin's Griffin}}</ref>
