1.
 Start with a 8.5x11 inches sheet of paper. |
2.
 Fold the middle fold. Unfold. |
3.
 Fold diagonally so you'll have a big triangle and beneath some "leftovers". Unfold. |
4.
 Fold the same way just to the other side. Unfold. |
5.
 Flip the paper and fold horizontally twards you. Use the middle of the X as pivot, and make the fold parallel to the lower/upper edge. Unfold. |
6.
 Flip back over. Now fold a fold named Praying Hands. All of this fold moves are shown HERE (click to see a series of pictures explaning how to fold it). |
7.
 This is after the Praying Hands fold. |
8.
 Take the top double layer of paper from the right half of the triangle and flip it to the left. |
9.
 Fold the triangle you just flipped to form half-a-diamond. (fold just what you flipped in the previous step) |
10.
 Flip the half diamond to the right. |
11.
 Now flip the top double layer of the left half of the triangle to the right. |
12.
 Fold the triangle you just flipped to form another half-a-diamond. |
13.
 Flip the top half diamond to the left, now you have a diamond. |
14.
 Fold the right half of the diamond so the slash-like ( / ) angle of the line will be along the main fold. |
15.
 Fold the left half of the diamond so the backslash ( \ ) angle of line will be along the main fold. Look at the picture - that's where it name came from. |
16.
 Fold the small top triangle of the 'kite' over the long one. |
17.
 Fold the plane to half, along the main fold, smooth side in. |
18.
 Fold the wing fold as shown at the picture. |
19.
 Set the dihedral angle be parallel to the horizon when the plane is flying. |
