Basically you are trying to Identify the paper of the 14 crains (some of the crains have the same paper) .
The reason for this challenge is just to have fun. Someone might ask why I have so many crains with such good paper, it is because when I get paper in a smaller size I like to fold crains because they are very nice and easy to fold
(all 14 crains)
