Hideko's Goldfish, opus 498
Medium: One uncut square of paper
Diagrams: Sea Creatures in Origami
Comments: Hideko and Tokinobu Mihara wrote one of the first English-language origami books, which contained the traditional fish that uses cuts. Tokinobu's Goldfish was an uncut version of this design; Hideko's Goldfish adds additional folds for a more organic look.
