From this form it is possible to fold both the flower and the frog. The simplicity of the diagrams of this form is deceptive. If you have paid attention on the pattern of this model, have noticed, that it most confusing.

Let's begin from the waterbomb base. Let's mark from the both sides two creases and push on them legs inside of the waterbomb. At the following stage the very difficult action is represented. I recommend at first to prefold the little creases and only then to make this transformation. Do not forget to repeat action with another three parties.

On this base form is based the classical model of the iris flower.
