Step 12: Let's create "new creases" that we can use. Fold the top two corners to the center of the X crease indicated by the black arrow. |
![Step 13](images/planes/hammer/13.jpg) |
Step 13: Unfold. |
![Step 14](images/planes/hammer/14.jpg) |
Step 14: Fold the top flap up at the red arrows where its edges meet the "new creases". |
![Step 15](images/planes/hammer/15.jpg) ![Step 15-2](images/planes/hammer/15-2.jpg) |
Step 15: Fold the left and right diagonal edges to the "new creases". |
![Step 16](images/planes/hammer/16.jpg) ![Step 16-2](images/planes/hammer/16-2.jpg) ![Step 16-3](images/planes/hammer/16-3.jpg) |
Step 16: Fold in diagonally one more time at the "new creases". |
![Step 17](images/planes/hammer/17.jpg) ![Step 17-2](images/planes/hammer/17-2.jpg) |
Step 17: Fold the top part down as shown. |
![Step 18](images/planes/hammer/18.jpg) |
Step 18: Turn the paper over. |
![Step 19](images/planes/hammer/19.jpg) ![Step 19-2](images/planes/hammer/19-2.jpg) |
Step 19: Fold the left half to the right. |
![Step 20](images/planes/hammer/20.jpg) ![Step 20-2](images/planes/hammer/20-2.jpg) |
Step 20: Make the wings by folding the right edge to the left edge indicated by the black arrow. |
![Step 21](images/planes/hammer/21.jpg) |
Step 21: Turn the paper over. |
![Step 22](images/planes/hammer/22.jpg) ![Step 22-2](images/planes/hammer/22-2.jpg) |
Step 22: Now fold the second wing to line up with the first wing. |
![Step 23](images/planes/hammer/23.jpg) |
Step 23: Open the wings. All done! Now let's learn how to fly the Hammer right. |
![Step 24](images/planes/hammer/24.jpg) |
Step 24: When unfolding the wings, make sure they are tilted up a bit like this so the plane can fly well. |
![Step 25](images/planes/hammer/25.jpg) |
Step 24: Hold this part of the plane and aim it slightly up so it can fly far. Now throw it hard! |
