Swivel fold

A swivel fold is a move where a flap pivots around a fixed point, dragging a small triangle of paper with it that is flattened by a short squash-like crease.

Fold one edge of the flap along the marked line while holding the pivot point still. As the flap rotates, a small wedge of paper is pulled out of line; flatten that wedge along a second short crease so it lies neatly. Swivel folds are used to narrow points, shape shoulders and hips, and reposition flaps without adding bulk.

Because two creases form at once, it helps to pre-crease the main fold first and move slowly so the wedge settles where the diagram shows. If the wedge buckles, the pivot has moved; open the fold and try again with a firm finger on the pivot. Swivel folds appear mostly in intermediate and advanced animals.

How to fold a swivel fold, step by step

  1. 1

    Find the pivot point in the diagram: the corner or spot that stays still during the move.

  2. 2

    Pre-crease the main fold line and unfold.

  3. 3

    Hold the pivot point firmly with one finger.

  4. 4

    Fold the flap along the main line; as it rotates, a small wedge of paper is dragged out of line.

  5. 5

    Flatten that wedge along the short second crease shown in the diagram.

  6. 6

    Press both creases flat.

Common mistakes and how to fix them

  • The wedge buckles

    The pivot moved. Open the fold, hold the pivot firmly and repeat slowly.

  • The wedge flattens in the wrong place

    Its crease has to run to the pivot. Guide the wedge with a fingertip until it lies where the diagram shows.

  • The flap ends up too narrow

    A swivel fold takes paper from the edge, so follow the fold line exactly instead of folding further in.

When you’ll use it

Swivel folds are a sign that a model is being shaped rather than built. They appear late in a sequence, when the main flaps already exist and need refining: a leg that narrows toward the foot, a shoulder that slopes, a point that tilts without adding thickness. Because they move paper sideways rather than stacking it, they are one of the best ways to keep a model slim. Many modern designers combine swivel folds with crimps and sinks to sculpt their animals. The easiest way to learn them is to fold a diagram that contains one slowly, watching which point stays still while the rest of the flap turns around it.

Swivel fold: questions

What are swivel folds used for?+

To narrow points, shape shoulders and hips, and move flaps to a new angle without adding much bulk. They are common in intermediate and advanced animals.

Is a swivel fold related to the rabbit ear?+

Yes. Both move two creases at once around a point. A rabbit ear forms a standing ridge that is laid to one side, while a swivel fold pulls a flat wedge along with the flap.

How is a swivel fold drawn in diagrams?+

Usually with a valley line for the main fold, a short second line for the wedge, and an arrow showing the flap turning around a fixed point. The next picture shows where the small wedge ends up.
