Outside Duck

Traditional

This simple origami duck will illustrate another of the most important origami techniques: the outside-reverse fold. It is called “outside-reverse” because a portion of the mountain crease will be flattened and then reversed to become a valley crease, as a portion of the model is pulled out and around the outside of the rest of the paper. Similar to the inside-reverse fold, the maneuver is used to change the paper angle at your choice.

Many beginning students stumble when learning these maneuvers from diagrams, despite its outward simplicity. The best way to master it is to study the video demonstration carefully and practice the maneuver. Again, you will need these skills and the ability to recognize the diagram indication for an outside-reverse fold (three valley fold lines) as you advance to more complex projects.

1 Begin with a Kite Base, back side facing up (see page 8). Use the existing center crease to valley-fold in half.

2 Outside-reverse-fold the narrow half of the model up to form the neck. Notice that the bottom ends of the arrows are inside the layers of the model. The dashed valley fold line indicates the desirable placement of the valley folds that will happen after the outside-reverse fold is complete. Look ahead at the next drawing to see the result.

3 Outside-reverse-fold the top point for the head.
