How can I create a 3D paper star decoration for my upcoming event?

To create a 3D paper star decoration, you can follow these steps:

1. Start with a square piece of paper.
2. Fold the paper in half diagonally to create a triangle.
3. Fold the triangle in half again to create a smaller triangle.
4. Fold the top corners of the triangle down to meet the bottom edge.
5. Repeat the same fold on the other side.
6. Fold the top point of the triangle down to create a smaller triangle.
7. Open up the folds slightly to create a 3D star shape.
8. Secure the folds with glue or tape.
9. Repeat the process with more paper to create additional stars for your event decoration.
