A somewhat challenging (high intermediate) Penguin designed by Oriol Esteve, from his most recent book "Fold With the Flow". This model is FULL of character, and can be finished with a number of different variations for the eyes and beak. You will definitely want to use square paper that is at least 24cm /9.4in on one edge.
"Fold With the Flow", by Oriol Esteve, published by Nicolas Terry
Recommend 24cm-35cm (~9in-14in) square of kami or other duo (black+white) paper.
