Snapology

make anything from strips of paper

This technique is quite easy to master, and gives you infinite options.

Read these pages from Faye E. Goldman’s book, Geometric Origami.

There are lots of tutorials on youtube, look them up :)

I found this tutorial useful:

What I like most about Snapology is that you can construct many kinds of solids:

Platonic solids

An icosahedron.

Archimedean solids

A snub dodecahedron.

A rhombicosidodecahedron.

A snub cube.

Catalan solids

These are the duals of the Archimedean solids.

A rhombic triacontahedron.
