This coin purse is an intermediate level origami project and should take approximately ten minutes to complete. To fold this model, you’ll need a piece of paper that has been cut into a true square, a ruler, pencil, and a suitable work surface.

Use any paper you like for your practice model. The standard sheet of copy paper (or similar) works well. Once you have mastered the model, then move on to colored or patterned papers. Just make sure that any paper you use is at least as heavy as the practice paper.

Your work surface must be hard and flat in order to attain the sharpest creases possible. This is very important, as the sharpness of your creases will play a major role in how well your model keeps its shape. Avoid soft, cushioned surface such as couches, pillows, or even your lap. Use a table, hardback book, or a similar surface.

- Position of the square of paper on your work surface so that its edges are facing up and down, left and right. If you are using two-sided paper, make sure that the color you want for the exterior of the purse is facing down.
- Use a ruler and a pencil to divide the paper into three equal vertical sections and three equal horizontal sections. You will draw two vertical lines and two horizontal lines.
- Bring the left edge of the paper over to meet the drawn vertical line that is closest to the right edge. Crease and unfold.
- Bring the right edge of the paper over to meet the drawn vertical line that is closest to the left edge. Crease and unfold.
- Bring the top edge down to meet the drawn horizontal line that is closest to the bottom edge. Crease and unfold.
- Bring the bottom edge up to meet the drawn vertical line that is closest to the top edge. Crease and unfold. The result should be a model that is divided into nine equal squares.
- Bring the top left corner of the model down toward the bottom right corner, stopping at the first intersection of horizontal and vertical crease lines that you come to. Crease and unfold.
- Bring the top left corner of the model down toward the bottom right corner, stopping at the second intersection of horizontal and vertical lines that you come to. Crease and unfold.
- Bring the top left corner of the model down to meet the bottom right corner. Crease and unfold.
- Bring the bottom right corner of the model up toward the top left corner, stopping at the first intersection of horizontal and vertical lines that you come to. Crease and unfold.
- Bring the bottom right corner of the model up toward the top left corner, stopping at the second intersection of horizontal and vertical lines that you come to. Crease and unfold.
- Rotate the model to the left so that the upper right corner becomes the model’s upper left corner.
- Repeat Steps 7-11.
- Pinch the top left corner from its point down to the first intersection of horizontal and vertical lines that you come to. The edges of the model that are adjacent to the top left corner should fold upward. Pinch to keep in place.
- Repeat Step 14 for the remaining three corners of the model. The result will be a model that has elevated curved sides and a square bottom. Position the model so that the edges of the square-shaped bottom are facing up and down, left and right.

16 Pinch together the paper layers that make up the model’s bottom left point and twist this portion up so that the point comes to lie flat and pointing to the right. The other points of the model should all come down as you perform this step.

- Press each of the remaining points flat so that a star-shaped model is formed. Four triangular flaps should form a square shape at the center. Position the model so that the top pointed flap points to the left and the bottom flap points to the right.
- Fold the top point down so that its tip touches the base of the bottom flap. Crease and leave folded. Repeat for the left flap, then the bottom flap.
- Tuck the left flap into the pocket created by the bottom flap that was folded up in Step 18. This closes the square-shaped coin purse.
