Start by folding the paper in half on both diagonals.
Then turn the paper over and fold the paper in half vertically and horizontally.
This step may be tricky if you've never done it before! Fold the left and right corners to the bottom, "collapsing" the model.
It should end up like this.
Fold the left and right corners to the center (top layer only!)
Do the same with the other side.
Fold the top point down along the folds from last step.
Turn the paper over.
Do step 7 again.
Unfold until you come back to this.
This is probably the hardest step of the model! Take the bottom corner (top later only) and fold it along the creases you made in steps 7+9. It should make a boat. Flatten the boat! Sry for bad vid :(
Do the same with the other side too. This is the model after you have done these folds.
Make sure the top has 3 points.
Fold the right "leg" to the right!
This is called an inside reverse fold. That means that you're reversing the crease and fold the paper inside itself (not really a good explanation :P)
You have made the neck+head of the crane!
Do the same thing on the left side as you did with the right, but don't make another head.
You made the tail of the crane! Almost done!
Fold the wing like so in the video, then match it with the other wing. (I'm not really good at explaining stuff like this, as you can see XD)
The crease should end up along the crane's neck.
Fold the "feet" (there's not really any guidelines for these folds)
CONGRATULATIONS! You made a crane! . .
. . . THAT FLAPS ITS WINGS!!!!
I hope you had fun making this! Show your friends!
