Then make a beak.
Move the tip in the direction of the arrow while pinching both sides at the blue circle.
If you change where you pinch the paper, the length of a beak will be changed.
Move the tip like this picture.
Pinch both sides in the direction of the arrows to fold the paper at the dotted line.
Fold the paper like this picture.
The last step is spreading wings.
First, spread wings a little like this picture.
There are two ways to spread wings.
Therefore, spread wings in the way which you like.
The first way is to make a crease on each wing-root.
While pinching both sides at the yellow circles, move the wing in the direction of the arrow to make a crease at the yellow line.
I recommend that you stop to fold the wing before making a crease neatly.
By stopping to fold the wing before making a crease neatly, the wing will be folded good.
Fold the other wing in the same way.
After spreading wings, it looks like this picture.
I recommend that you spread wings in the first way when making “連鶴/Renzuru”.
The second way is to swell a crane’s back.
Push the crane’s back from top while spreading wings in the direction of the arrows.
After pushing the crane’s back, it look like this picture.
A paper crane is complete!
This crane is that I spread wings in the first way.
On this site, I’ve considered and posted how to fold “連鶴/Renzuru”.
Renzuru means connected-cranes which are made of only one paper without glue and tape.
I recommend the link below if you have never folded Renzuru!
