The steps of making a windmill are as follows:

1. Preparation materials: First, you need to prepare a square piece of paper, scissors, pins and sticks. Choosing thicker paper can make windmills more durable.

2. Folding paper: Fold the square paper diagonally in half, and then fold it again, so that the paper is divided into four equal triangles.

3. Paper-cutting: Starting from the apex of each triangle, cut about two-thirds of the length to the center, and be careful not to cut it completely. In this way, eight blades of the windmill are formed. Be careful when using scissors, and don't let children do this step without adult supervision.

4. unfold the paper: unfold the paper carefully, and you will see that the eight leaves have been evenly distributed at the four corners of the square.

5. Fix the windmill: pass a pin through the center of the paper to ensure that all the blades can rotate freely. Then, fix the other end of the pin on the stick. When fixing the windmill, make sure that the pin passes through the center of the paper and is fixed firmly to prevent the windmill from falling off when rotating. The length of the stick can be adjusted according to your needs.

6. Finish the windmill: Now, your windmill has been finished. You can blow gently or put it in the wind and watch the blades of the windmill turn.
