In plush toys, how do we create the appearance of one or several ear piercings?

There are generally two methods.

One method is to directly make a small hole or not make a hole at all, and then attach the earrings after the toy is finished.

The other method is to embroider the ear piercings with black thread, making it look like earrings from a distance.

This technique is also commonly used for moles.

When there is one or more moles, they are embroidered to look like moles on a person's face from a distance.
