As with all good origami, you know you are getting close when it
looks like you haven't done very much. All we have now is an upside
down triangle. Turn it upside down (um, rightside up ?)
Hold the model between your fingers, in the middle. Your crane
is here, it is just hiding.
Talk nicely to it, and pull the head up from between the wings
in the front. The paper will roll and bulge out near the bottom
right, try not to interfere.
