How to draw shells?

1. First of all, on the prepared paper, let's draw a slightly inclined ellipse, leaving a little blank for the ellipse, as shown below.

2. In the blank part of the ellipse just drawn, we draw two small downward dashed lines to connect the ellipses, thus drawing the general shape of the shell, as shown in the figure below.

Here we are going to draw a pattern on the shell. Near the edge of the shell, we draw a short line, which is very simple, as shown in the figure below.

Through the above steps, we have drawn a shell. Here we begin to draw the second shell, and draw an inverted water drop on the paper, as shown below.

5. At the edge of the inverted water drop shape, we then draw the shapes of two inverted water drops, as shown in the figure below.

6. Here we continue to draw inverted water drops, which is similar to the previous two steps, as shown below.

7. What is drawn here is the shape of a water drop, but the inclination angle of the water drop is different. Please refer to the picture below, it is not particularly difficult.

8. The last step is to paint the shell with your favorite color. Here, everyone paints according to their favorite color, so that the shell is painted.
