Fold and Soar is a small paper airplane project: folding guides you can take to a kitchen table, and a free 3D app for seeing each fold move.
What is here
Forty-four plane guides, one for every design in the app, each with a diagram for every step and a shape check. Five workshop articles cover paper, troubleshooting, choosing a design, running a fair test and the physics of a glide. None of it needs an account, and the written guides work without the 3D app.
Who makes it
The website and app are made by Takayuki Hoffman and published under the Fold and Soar name. The app (also called Skyfold) combines a paper-folding model with a flight simulator.
How the diagrams are made
The diagrams are not drawings of someone's hands. The site's build runs the app's own fold engine for each plane, records the paper at every step, and draws it: the layers that move, the fold line, and where the flap lands. That is why the website and the app always agree, including the measurements. More on how guides are made and checked.
A model and a real plane are different
The simulator is useful for seeing a fold or exploring a trim, but hand-folded planes have wrinkles, loose layers, damp paper and imperfect throws. We keep simulation and real flights separate, and do not present simulated distances as records.
