How to Fold an Origami Pinwheel
The origami pinwheel is a flat four-bladed model folded from the traditional windmill base that can be pinned to a stick so it spins in the wind. It is an intermediate model taking about six minutes, with one careful step where hidden corners are pulled out.

- Paper
- A square of 15–20 cm (6–8 in); duo paper with a different color on each side shows the blades best
Start white side up and crease the square in half both ways, opening after each fold.

Step-by-step instructions
The same 6 steps as the animation above, written out so you can fold away from the screen.
Step 1
Start white side up and crease the square in half both ways, opening after each fold.
Step 2
Bring each edge to the middle crease and unfold, dividing the square into a four-by-four grid of small squares.
Step 3
Crease both diagonals corner to corner and open.
Step 4
Bring the side edges in so they meet along the middle crease.

Step 5
Now bring the upper and lower edges to the middle too. As they close, draw the hidden inside corners outward and press them flat as triangles. The shape you have is the windmill base.
Step 6
Fold the upper left flap up and the lower right flap down, so all four blades point in the same rotational direction.
Finished
The pinwheel is done. For a spinning toy, push a pin through the middle, thread a bead behind it, and fix it into a pencil eraser or wooden stick; a breeze will set it turning.
About the origami pinwheel
The pinwheel is a traditional origami toy with four blades that turn in the same direction around a square center. Mounted loosely on a stick, it spins in the wind, and even unmounted it makes an attractive flat decoration for gift wrap, cards or a window. It has long been a summer favorite for children and a colorful touch for garden parties. Paper that is different colors on each side works especially well here, because the blades alternate between the two colors and create a bold, swirling pattern when the model turns.
The model is built on the windmill base, a traditional starting form made from a grid of sixteen squares plus two diagonal creases. Folding the edges in and guiding the hidden corners out teaches controlled squash folding and shows clearly how a crease pattern predetermines a shape: when the grid is accurate, the paper almost collapses by itself. Turning two of the flaps in the last step demonstrates how a very small change produces rotational symmetry, which is what lets the finished pinwheel catch the wind from the front and spin.
For a spinning toy, use a pin with a bead behind the paper and push it into a pencil eraser or a wooden dowel, leaving enough slack for the blades to turn freely. If you enjoy moving models, the Jumping Frog is a natural companion. The Masu Box offers more practice with the same center-line grid, and the Lucky Star is another decoration that looks great in bright colors. When the windmill base feels easy, you are ready to take on the Paper Crane and its petal folds.
Origami pinwheel: questions
Will an origami pinwheel really spin?+
Yes, if it is mounted loosely. Push a pin through the center into a pencil eraser or stick, leaving a bead or small gap behind so it can rotate freely. Point the front into the wind or blow on it.
What is the windmill base?+
The windmill base is a traditional origami starting shape with four flaps arranged around a square center. It is folded from a grid of creases and is used for the pinwheel and several other traditional models.
Why won’t my windmill base flatten properly?+
Usually the diagonal creases are weak or the grid is uneven. Re-crease the diagonals sharply, then fold the top and bottom edges in slowly while guiding the hidden corners out.
Is the pinwheel safe for small children?+
The paper model itself is safe, but the pin is a hazard for young children. Adults should attach it, or use a brad fastener or glue dot instead of a sharp pin.

Jumping Frog
The origami jumping frog is a traditional action model folded from a stiff rectangle that springs forward when you press and release its back. It is an intermediate model that takes about six minutes, mostly for the collapse and the zigzag spring.
Masu Box
The masu box is a traditional Japanese square box folded from a single sheet that locks together without glue. It is an intermediate model that takes about eight minutes, with one three-dimensional step where the walls are raised.
Lucky Star
An origami lucky star is a tiny, puffy five-pointed star made by knotting a long paper strip into a pentagon and wrapping it. It is easy and takes about three minutes, though the final puffing step needs a light touch.
Paper Crane
The origami crane is the traditional Japanese orizuru, a bird with spread wings folded from a single square without cuts or glue. It is an advanced model: expect about 15 minutes for your first one, mostly spent learning the petal fold and inside reverse fold.
