Diagram Book

PCOC will be publishing a diagram book in both print and PDF formats.

The 2023 PCOC Model Collection collects 61 diagrams, crease patterns, and articles from 49 authors from around the world, all focusing on the theme PLAYFUL & PRACTICAL. We are very excited to share this fun and diverse collection with you.

In 198 pages, you will discover models that range in difficulty and diagramming styles. You’ll also find some old jewels mixed in with the new. Our models move, swim, fly, make noise, beat, are playable, wearable and can be used to organize and store objects, even to frame photos, and so much more! Our articles talk about practical models, the design process, and the playful aspect of teaching origami. In the very last section, “Biographies”, you can learn more about our creators.

Here is the Table of Contents (PDF).

In-person attendees of PCOC 2023 can order either the print book or the PDF (or both) as part of their registration. Ordered print books may be picked up at check-in. PDFs will be delivered electronically to your website account by October 26, 2023.

After PCOC, people can order the print book from The Origami Source using the link below. Orders will be taken until supplies sell out.

After October 26, the PDF version of the book can be ordered from The Origami Source; it will then be delivered immediately to your website account.
