Outside Reverse Fold

inside reverse fold
The Outside Reverse Fold is commonly seen in the making of origami animals. In particular, the head or feet are made by executing these series of moves. The result is similar to that of an inside reverse fold; however, the difference is that in the outside reverse fold, the paper wraps around the model (on the outside of the model). In contrast, the inside reverse fold lies in between the existing layers of paper.
