Every year I fold origami cranes with the 4th graders at the school where I work.
Every year I enjoy it a little bit more. I think 4th graders are wonderful!
You can see more of their paper cranes here. I started my paper crane project a few years ago . . . not intending for it to take me so long - but I am still at it. I am pretty sure I have folded over 1000 cranes outside of the ones I have folded for my project . . . and usually after I do this with the 4th graders - some of the kids go "crane crazy" for awhile . . . so I will probably be sitting with some of them at lunch recess folding more.
