[5] Curl the top layer of paper so that point A extends past edge XY but do not crease. This will create a triangular flap. The top edge of this triangular flap should intersect point Z, point Z is located slightly below the halfway point of edge XY. |

[6] This is how the model should look after completing step 5. Note that you have not creased edge CB yet and that the top edge (edge BA) of the triangular flap intersects point Z. For Step 6, rotate the model so that edge CA is horizontal. |
