Origami bases are often the starting point of models and projects. The Frog Base is one of a group of traditional bases that are used in both traditional and more modern origami design. It gets its name from the traditional origami frog that can be made from it. It basically consists of four long flaps joined to a short one. At first glance this would make it ideal for making four-legged animals or human beings (one flap each for legs, arms and head). Most people have tended to use the Bird Base instead of the Frog Base as the small flap on the Bird Base is not as thick as it is on the Frog Base, which makes it easier to work with.

Crease Pattern

Like the Bird Base, the crease pattern for the Frog Base occurs frequently as a component in the design for much more complicated origami designs. It is worthwhile becoming familiar with it even at an early stage as this builds the confidence to work with crease patterns over time. By learning some of the ‘building blocks’ that make up the crease patterns of more complex models, it will be easier to interpret and understand these crease patterns.
