Theme for the PCOC 2025 Diagram Collection

Hello, paper-folding explorers! We invite you to journey into the world of Money Folds & Modulars.

Whether you’re transforming a single bill or assembling multiple folded units, we’re excited to see how you elevate these forms into something truly extraordinary.

Let’s start with money. Take those rectangular bills and fold them into something worth more than before — whether it’s a playful duck, an action-packed model, or even a modular money model (extra credit). Your creativity is the currency, and we look forward to seeing your newly folded fortunes.

As for the modulars, it’s all about connection. Start with two or more folded units, whether from squares or other shapes, and bring them together to create something greater than they were alone. No glue—just the simple beauty of paper and skill, working in harmony.

And that's it for our 2025 theme of Money Folds & Modulars. We look forward to reviewing your design submissions. Thank you for participating!

And, of course, Happy Folding!

Diagram Requirements

Test-Folding

Find at least two people who will try to fold the model following your diagram before you submit it. Listen to what they have to say and correct the mistakes. It will make our work go much smoother and faster.

Credits

Your diagram should include the name of the model, creator, diagrammer, and photographer (if you use photos).

PDF Format

Send us a single print-ready PDF file (300 dpi) with embedded fonts.

  • Embed fonts when generating the PDF.
  • If embedding doesn’t work correctly, convert all fonts to outlines prior to generating the PDF.

Page Dimensions

  • Letter format (11 x 8.5 in) with margins: top 0.5 in; bottom, left, and right: 0.625 in.
  • Don’t put anything outside of the page margins.
  • The only exception is if you want to have a snake going to the edge of the page. In that case, you need to use a bleed area (0.125 in). Please make sure that the snake reaches its border. Also, you have to save a file as a PDF with a bleed, otherwise, it will be lost.

Print

  • The book will be printed in black & white. Your diagram can be done in colors though, we will do the conversion ourselves.
  • If you use more colors, make sure they look different enough when printed in B&W.
  • Preferably use a white background and black color for texts.
  • Use conventional styles and symbols for your diagram.
  • Don’t use a line thinner than 0.25 pt as it may be lost during print.

Templates

We prepared templates for you in Adobe Illustrator, Affinity Designer, and Inkscape. They have the correct page size, with margins and bleed region set. It’s not necessary to use them if you follow our guidelines.

How to Submit

Fill out the submission form below, which will include the file upload. You can submit up to three works by the same creator by submitting the form for each work.

You will be required to submit your bio in the form. It will need to be a single paragraph, 750 characters or fewer). You only need to include the bio with one of your submissions.

Please keep in mind the deadline is Sunday, June 1, 2025, 12:00 pm EDT. Consider submitting sooner in case we have some follow-up questions.

We will review all submissions and notify everyone of accepted items for publication by Monday, June 30, 2025 EDT.
