A. Although the Rocks brush was specifically designed to address the problem of constantly having to redip a brush in paint during the long and painstaking poroess of rendering rocks, it is equally suitable for rendering any part of the miniature painting. The process of rendering the rocks and hair, for example in the fine, lovely beards adorning the faces of the men are fairly similar. And you can use them for fine details throughout the miniature or illumination piece. It’s also good for line work.
