This Week's Folds (18 Feb 2020–24 Feb 2020)

Clownfish by John Montroll

From Nick Robinson (ed.), Origami Fish. (I have this book only in electronic format.)

If I understand the Google translation of the text on the page, this model is based on a composite model by Toshio Chino. In Kunihiko Kasahara's Viva! Origami.

Narwhal by Manuel Sirgo Álvarez

From Manuel Sirgo Álvarez's Origami Menagerie.

Koala by Yoshihide Momotani

From Steve and Megumi Biddle, The New Origami.

The Week's Folds (11 Feb 2020–17 Feb 2020)

Columbine by Benjamin John Coleman

Made with two sheets (one is 1/4 size of the other). From Benjamin John Coleman's Origami Bonsai.

Tumbling Chan by Harry Weiss

From Samuel Randlett's Best of Origami (I do not own this book, just a photocopy of it.)

Quilt (four-petaled flowers and crosses) by Tomoko Fuse

Sixteen small squares and one large square. From Tomoko Fuse's Origami Quilts.

Flying Heart by Francis Ow

From Francis Ow's Origami Hearts.

Sparrow by Edwin Corrie

Yes, the directions clearly say to use paper colored the same on both sides. I used what was handy. From British Origami #145 (December 1990)

Balloon by Steffen Gnam

I could not get Gnam's basket to work, so I improvised one out of a square 1/4 the size of the balloon. The balloon does not stay in the basket, however—but I suspect Gnam's did not stay either.

From the British Origami Society Autumn Convention 1984.

Horse by Akira Yoshizawa

From British Origami #142 (June 1990). (The photo on the cover is of a different Yoshizawa horse made from two pieces; the one I folded is a one-piece model. Both are diagrammed in the magazine.)

Recent folds (5 Feb 2020–10 Feb 2020)

Pyramid tent by Jonathan Walton

An incredibly difficult fold. I ended up using the "smash and hope for the best" approach when I could no longer understand the diagrams. From Eric Kenneway's Origami: Paperfolding for Fun.

Seated Buddha by Kunihiko Kasahara

From Kunihiko Kasahara's Creative Origami.

Gorilla by Akira Yoshizawa

I was almost too embarrassed by this to post it. The face is hard! But I guess it requires "softer" paper (maybe dampened?—many folders advocate "wet folding") and lots of practice!

From Akira Yoshizawa's Origami Museum 1: Animals

Dragon by Robert Neale

From Samuel Randlett (ed.), The Flapping Bird (issue number 5)

Beniire cube (traditional)

Made from three squares. From Kunihiko Kasahara's The Art and Wonder of Origami.
