Fox's head by David Brill

From British Origami no. 153 (April 1992). Another failed fold. How the heck does the thing hold together? 

Sparrow by Jan Willem Derksen

From British Origami no. 154 (June 1992).

Cricket by Yoshihide and Sumiko Momotani

From Yoshihide and Sumiko Momotani's Origami: Image and Creation. (This is yet another failure in a long line of attempted folds this month; I can't get the model to look anything like the final drawing.)

Puppy 2 by Edwin Corrie

From British Origami no. 152 (August 1992).

Tweedledum and Tweedledee by Nick Robinson

Made with two squares of paper. From British Origami no. 157 (December 1992).

Japanese raccoon dog/tummy-drum by Yoshihide Momotani

From Yoshihide Momotani's Trick Origami. I'd have to classify this as a failed model. The paper is very thick around the head; I gave up trying to shape it. Need much bigger, thinner paper.

Baby starling (traditional or else Murray and Rigney)

From a piece of paper shaped like a 5-pointed star. From William D. Murray and Francis J. Rigney's Fun with Paper Folding and Origami (I have two copies of this; the older printing is entitled Paper Folding for Beginners).

Sampan by Max Hulme

Made from a 2-by-1 rectangle. From British Origami no. 165 (April 1994)

Easy origami rabbit, author uncertain

From a YouTube video at https://www.youtube.com/c/MagicPaperOG, author unclear.

Raven by István Kiss

From British Origami no. 166 (June 1994).

Chicken by Jirō Ueda

From Jirō Ueda's Fun Origami. I made a few extra cosmetic folds to the beak. This appears to be a fairly old book—copyright date is 1955.

Quail by John Montroll

From John Montroll's North American Animals in Origami

Moth by Jack Botermans

From Jack Botermans's Paper Flight.

Table (traditional Chinese?)

From Maying Soong's The Art of Chinese Paperfolding.

Five-Four Tesselation by Eric Gjerde

I think I have the manual dexterity to finish this, but I'm not sure I have the time or the patience (and this was a beginner's project!). From Eric Gjerde's Origami Tesselations.

Parthenon by Alison Jenkins

Made from about a dozen white washcloths. From Alison Jenkins's King Size Towel Origami

Many folds from the past several weeks/months

Pushmi-Pullyu by Florence Temko

Made from two squares. From Florence Temko's Paper: Folded, Cut, Sculpted

Japanese Macaque by Jun Maekawa

From Jun Maekawa's Genuine Origami. (I have this only in e-book format.)

Twelve-Winged Spinning Top by Kunihiko Kasahara

From Kunihiko Kasahara's Amazing Origami. (I have this only in e-book format.)

Gazelle by Akira Kawamura

Made from a 42 x 14 rectangle (I used graph paper). From Akira Kawamura's Origami Animals in the New Style.

To me, this is not origami, or at least, not the kind of origami I want to do—although I have to admit, it bears a striking resemblance to Neal Elias's "box-pleating" technique (as I remember it, anyway).

Four intersecting triangles by Philip Chapman-Bell

Made from 12 pieces of paper proportioned 1:√3.  From Imagiro, vol. 1, no. 6 (Sep–Oct 1994)

Cube by Haruo Hosoya

From Pixel, vol 2, no. 1 (Mar/Apr 1991). (As I look at the photo I think maybe I assembled it incorrectly.)

Venetian mask by François Domergue

From The Corsican Origami Society Bulletin #9, Aug 1989

Shining Alice by Michael Shall

From The Newsletter for Origami USA, #51, Summer 1995.
