Christmas tree with seven thousand paper cranes
Christmas tree with seven thousand paper cranes is known as the world tree of hope. Every winter, in December, hundreds of paper cranes flock to San Francisco to decorate the tree in the world encouraging. The project, which started 5 years ago, merged two traditions – western and eastern, as cranes build their nests on the Christmas tree. Origami has not only a decorative function – each of them is written wishes. Paper birds for the Christmas tree are signed by celebrities.
