-one slice of square paper
Now open and smash one of the corners. Repeat on the back. This is probably called a base (crane?) but it doesn't matter much, just make it look like the pictures.
Re-arrange the model by turning the layers like pages in a book, then fold the right and left sides in to meet at the middle crease. Flip the model over and repeat on the other side.
Re-arrange the model again to look like the last picture in this step.
Fold the tip of the last part folded down to meet the bottom crease of that section.
Fold the flappy thing inside the pocket.
Flip the model over and repeat all these things.
Fold the top tip down to meet at the bottom point then bring the tip back up to meet at the line where the colored and white paper meet.
Tuck this section into the pocket.
Flip the model over and repeat the folds.
Open the box up and crease to shape it. Now fill it will awesome things!
