This fascinating technique is the creation of three-dimensionalfigures from triangular origami modules - invented in China. The whole figure is assembled from a set of identical parts (modules). Each module is folded according to the rules of the classic origami from one sheet of paper, and then the modules are connected by inserting them into each other. To collect a vase you need quite a lot of modules. Therefore, it's easier to make a big company. Also, this kind of creativity is great for teamwork in school. You can experiment with different types of paper. Suitable office paper in different colors, coated color paper. Sometimes they add such figures from magazine cuttings and candy wrappers. Poorly suited school color paper, because it is too thin, loose, breaks and tears at the folds. Good luck to all in creativity!
