Folding basics
These moves appear in many models. Each model’s folding screen shows them in 3D.
- - - Blue dashes: fold toward you — — Orange dashes: fold away
Valley fold
Fold the paper toward you so the crease sinks like a valley. Shown with blue dashes.
Mountain fold
Fold the paper away from you so the crease rises like a mountain. Shown with orange dashes.
Fold and unfold
Fold to make a crease, then unfold. The crease guides later steps.
Turn over
Flip the whole paper over. The paper turns, not the camera.
Inside reverse fold
Push a point between its own layers to change its direction. Pre-crease first to make it easy.
