A Czech-language independent project explaining how flat sheets become moving, foldable books.

Landing page captured for the 2026-09-09 issue.

Field notes

The project organizes paper engineering around a small set of recurring mechanisms, then follows them into construction details such as fold geometry, material grain, scoring, mock-up testing, and binding. Its examples include a rotating disc mounted on a paper rivet or circular slot, plus a sliding tab whose groove needs reinforcement and an end stop. The text frames these as workshop observations rather than a service offer.
