1. Draw a curve to form a semicircle, which is a cloud. Draw a small curve on the left side of the semicircle, which has a short overlap with the semicircle to form a fluffy cloud.

2. Draw a short curve with a short overlap with the semicircle on the right side of the semicircle. The two short curves around the semicircle should look high and low.

3. Draw a series of small connection curves from the left side of the cloud to make them horizontal.

4. In the horizontal direction, continue to draw a short curve to the right and connect it to the curve on the right, thus forming a closed cloud.

5. Erase the cloud part inside other curves.

6. Draw several groups of connected curves or small spirals inside the cloud to make the shape of the cloud more fluffy.

7. Draw a small cloud behind the first cloud and enclose it with curves of different sizes to form an irregular shape to show a fluffy shape.

8. Draw a short curve or a small spiral inside the second cloud to supplement the details of the cloud. Then draw some connected curves on the right side of the first cloud to represent another cloud.

9. Finally, color the clouds. Clouds are usually white or light blue, or painted black, gray and brown to represent dark clouds. Or paint it pink, purple, orange or red to represent the clouds at sunrise or sunset.
