Okay I haven't truly explained why I changed from being nonchalant about origami to slightly obsessive over origami paper cranes. I'm in the mood for some explanation work.. so, I guess it's mainly awakened due to my fascination towards its legend and my curiosity on my Japanese roots. The ancient Japanese legend promises anyone who folds a thousand paper cranes, a wish. It is believed that the wish is granted by none other than a crane. You see, in Japanese beliefs, the crane is a mystical, holy creature and is said to live for a thousand years. Figures. One paper crane for each year that the crane lives, therefore, a thousand paper cranes are made. Oh and all the paper cranes are to be made within one year by the person who wishes to have his/her wish granted at the end. No help is to be received or asked. Cranes that have been given to, or have been given away to others are not countable. A thousand paper cranes are to be kept by the person wishing at the end :) the origami paper cranes are to be held together by strings.
The thousand paper cranes is popularized by the story of a young girl named Sadako Sasaki who was exposed to radiation from the atomic bombing of Hiroshima. She developed leukemia at the age of 12. Having believed in the legend, she started folding paper cranes in goal of making a thousand of them. She only managed to fold 644 before her death.
