A square, a crease, a crane

Paper rewards clear decisions. Align the edges before pressing a crease, unfold deliberately, and keep track of which layers belong to the next step. The traditional crane is a patient introduction to bases, petal folds and reverse folds. Use the viewer to pause at each stage rather than racing toward the finish.

Fold a traditional crane

Choose your values, then try the tool.

Keep the opening downward until the bird base is formed; turn the model over when asked.

Fold lines record a sequence: a crease can prepare a movement several steps ahead.

Choose a forgiving square

Begin with a true square of paper that is thin enough to fold several times without becoming bulky. A contrasting colour on each side helps you see which face is showing. Very small sheets make the early learning harder because a slight alignment error becomes a large part of the model. Place the paper on a smooth surface and keep your hands clean and dry. If the starting sheet is not square, trim it accurately before folding; repeatedly correcting uneven edges during the model only makes the later layers more confusing.

Read the crease language

A valley fold brings the visible sides toward each other, while a mountain fold sends the crease away. Turning the paper over reverses how that same physical crease is described. Crease lines, movement arrows and finished outlines have different jobs in a diagram, so identify them before moving the paper. A preparatory fold may be opened again immediately; its purpose is to leave a useful reference. Press a crease only after the corners and edges are aligned. A crisp, deliberate crease is easier to reuse than several hesitant lines close together.

Understand the bird base

The crane begins by collapsing prepared creases into a square base with the open edges below. Folding the lower side edges toward the centre creates the references for a petal fold. When the lower point lifts, the sides fold inward along those prepared lines and the shape becomes a long diamond. Repeating that action on the reverse produces the bird base. Pause here and compare the layers on both sides. Two long points will become the neck and tail, while the broader upper points will become the wings.

Finish with gentle reversals

Narrow the lower points evenly before raising them. An inside reverse fold changes the direction of a point by opening its layers slightly and reversing the creases between them. It is a controlled change of structure, not simply bending the point sideways. Use one raised point for the neck and the other for the tail, then reverse the neck tip again to form the head. Lower the wings gently and shape the body without pulling hard on a single layer. Small differences in the final angles give each crane its own character.

Words to work with

Base
A folded starting structure from which several different models can be developed.
Petal fold
An opening-and-closing movement that lifts a point while the side edges fold inward along prepared creases.
Reverse fold
A change in the direction of a point made by reversing the creases between its layers.
