This little penguin is a teaching model designed by Valerie Vann (She is best known for her magic rose cube). And it does teach quite a few folds – crimps and sinks and double rabbit ear and close sinks. It looks simple but it does involve some effort. Best to try out on a larger square before trying out on a smaller on.
The penguin can stand by itself, just spread the base and it will stand upright; or it can also be used as a bookmark. And it makes a very cute bookmark too
