To kick off World Origami Days we are celebrating the birthday of a woman who played a huge role in bringing origami to the West. October 24 is the birthday of Lillian Oppenheimer (1898-1992), who founded the first origami group in America. She was also one of the founders of the British Origami Society and OrigamiUSA. A dynamic woman, she was delighted in the magic to be found in a piece of paper and wanted to share it with the world. She famously held folding events in her apartment in NYC, and there are still those among us who attended those events. Happy Birthday, Lillian!

We will learn from Wendy Zeichner and Marcio Noguchi about the major organizations in the US and Japan and how World Origami Days became important.

Welcome to World Origami Days (WOD) To kick off the 19 days of folding we will begin with a class by PCOC 2025 guest of honor, Jun Maekawa. Maekawa san will teach us 2 models: Globe and Doll. To fold the globe please print out the pdf attached to the description. The doll figure is a unique design using Leonardo da Vinci's Vetruvian Man for inspiration. As in previous WOD years, these kick off class designs are meant to be used as props for the pictures you will take of the models you fold throughout the days. Please post using #WorldOrigamiDays2024.

While on vacation this past summer, Jannie created a series of envelopes with different decorations on each.

Six sheets of 6" (15 cm) kami, all the same color.

This is a modular design, an "edge" unit, which can be used for any convex polyhedron. We'll fold six units (the simplest possible polyhedron, a tetrahedron), but one can easily use it for large ones. One based on the edges of a cuboctahedron (24 units) is pictured.

Day 6. Cat-O'-Lantern v1
October 29, 8:00 pm to 11:00 pm EDT
Level:
Complex
Presenter: Michelle Fung
Host(s):

Creator(s):
Michelle Fung

12" (30 cm) square paper with different colors on opposite sides. The paper should be about as thin as standard origami paper.

True to her style, Michelle designed this cute yet complex model of a cat and jack-o'-lantern. Surprisingly they are both folded from the same uncut square. Michelle will be a PCOC 2025 guest of honor.

Day 7. Hina Doll Boxes
October 30, 8:00 pm to 11:00 pm EDT
Level:
Intermediate
Presenter: Anne LaVin
Host(s):

Creator(s):
Akiko Yamanashi

Recommended: 6” (15 cm) (or larger)
Two sheets of solid color (lower bodies)
Two patterned sheets (kimono & upper body)
One black sheet (hair)

Tools: Cutting tool (Paper will be cut proportionally at the beginning of the class)

These are delightfully clever decorative boxes, made to look like the traditional "Hina Dolls" from the traditional Japanese "Hinamatsuri" or Doll's Day Festival. They represent a traditionally-dressed Emperor and Empress of the Japanese Imperial Court.

Day 8. Narwhal
October 31, 8:00 pm to 11:00 pm EDT
Level:
Intermediate
Presenter: Michael G. LaFosse
Host(s):

Creator(s):
Michael G. LaFosse

8-10" (20-25 cm) square. You can use any quality you like to fold, even foil. Color recommendations: White through dusky gray; speckled with black if you can manage it. The back side should be white--this is a color-change model; the "unicorn horn" will be white.

Narwhals are unique among toothed whales. The male is distinguished by his protruding, unicorn-horn-like two front teeth. The tail flukes are also unusual; this origami model satisfactorily represents their unusual profiles. This 3-D model may be wet or dry-folded.

Day 9. Powers of Two Quilt
November 1, 8:00 pm to 11:00 pm EDT
Level:
Intermediate
Presenter: Charlene Morrow
Host(s):

Creator(s):
Charlene Morrow

2 types of units (all squares; all same size; only one side shows) Recommended to learn with 3" (7.5 cm)

Color/Pattern 1: 1 sheet; Color/Pattern 2: 2 sheets; Color/Pattern 3: 4 sheets; Color/Pattern 4: 8 sheets; Connectors (they are the black pieces in the photo): 14 sheets.

It would be fine to make this model with 15 all of the same color squares (i.e., not different colors/patterns) and 14 of a contrasting color for the connectors. The best paper weight is regular kami to tant, not heavier.

Char has developed an ingenious way to honor someone's birthday. Through a modular quilt and some mathematics some aspect of the model matches the age of the birthday celebrant. Char will show some examples and will teach the version of this quilt that is a birthday gift for an 8 year old (8 = 2 cubed), or for a 29 year old (there are 29 pieces of paper in this quilt).

Day 10. Trashbot
November 2, 12:00 pm to 3:00 pm EDT
Level:
Complex
Presenter: Brian Chan
Host(s):

Creator(s):

A square of foil-backed paper, at least 12" (30 cm).

This familiar little trashbot was inspired by the Pixar film, "Wall-E". When folded from foil paper, the eyes and arms can be posed expressively.

Day 11. Seahorse
November 3, 12:00 pm to 3:00 pm EST
Level:
Complex
Presenter: Richard Ellison
Host(s):
World Origami Days Team
Creator(s):
Eric Joisel

A square 10-14" (25-30 cm) tissue foil or foil backed paper.
A tool with a short, flat, thin edge, possibly a cut up, cancelled credit card or a spent gift card. Richard uses the flat bladed end of his Chartpak adjustable burnisher. A flat paint scraper and one or two small clothespins or clamps could also be useful.

If you have ever heard origami described as something like “sculpture from paper,” this design is truly an example of that. Eric Joisel’s Seahorse is a work of origami with a simple base and extraordinary shaping. The base can be formed in minutes, but completing the final form can take an hour or more. The result will be as much a test of your ability to sculpt, as it is of your ability to follow instructions.

Day 12. Poinsettia and Patchwork Wreath
November 4, 8:00 pm to 11:00 pm EST
Level:
Intermediate
Presenter: Miyuki Kawamura

Level:

25cm sheet of kami (or other duo color paper)

This cardinal is a complex non-uniaxial hex pleating (HP) model, featuring color changes and a puffy 3d belly. The grid is a 12x12x12 hex grid on square paper.

This is a pretty difficult model even compared to other hex pleated designs, so having experience with box pleating would be helpful if this is your first time using hex pleating.

4 sheets, 15 cm X 3, 25 cm X 1 (Elephant Hide is best. (110-120 gsm)

This tessellation molecule is made from straight lines only, but the result is surprisingly curvish. Hilula means festivities, making it appropriate as we celebrate World Origami Days.
