How is the brush kept in the dry-brush technique?

Correct answer: With little moisture and little paint

In dry-brush technique, the brush contains very little moisture and only a small amount of paint. The relatively dry bristles catch mainly the raised areas of a textured surface, creating broken, scratchy or uneven marks. Therefore option D is correct. A water-soaked, heavily loaded or oil-filled brush would produce a wetter, smoother or different effect and would not follow the governing principle of dry brushing.
