1. Fold the paper in half lengthwise and then unfold.

2. Fold the two sides into the middle.

3. Fold the paper in half the other direction and orient the folded edge at the bottom. The flaps from the previous fold should be on the outside.

4. Fold the bottom two corners in to the middle to make a triangle shape. Unfold.

5. Accordion fold the corners into the middle, tucking the triangle pieces inside.

6. Fold the front piece down, aligned with the corner on the outside edge. Make a strong crease and fold back up so it looks like step 5.

7. Reach inside the two vertical folds and pull them apart. At the same time, fold down along the crease made in step 6.

8. Fold it all the way down along that crease and flatten out the wings.

9. Flip it over and fold the top two middle flaps diagonally to the outside.

10. Fold the bottom left edge up to the middle. Repeat with the right side.

11. Fold the bottom point up. It will naturally want to fold along a line formed by the inner layers.

12. Fold the entire paper airplane in half.

13. Optional lock-fold to keep it held together: Reach inside and fold the tip of the small triangle piece over to one side.

14. Fold out both sides to form the wings. The fold should be parallel with the middle crease and about one third the length of the front of the airplane.

15. Fold the cat's ears up on both sides.

16. Fold up the wingtips in the back of the airplane. If using A4 sized paper, you may want to fold these down instead.
