There are 15 brushes in this newest collection, divided into three related categories: hair, fur and stubble. The hair brushes combine both straight and curly hair and are generally designed for creating human hair effects. And the straight brushes are designed to create the strands in the direction of the brushes stroke. The fur brushes, on the other hand, are designed for creating animal fur effects. All of these brushes are slightly wavy, and the strands are drawn at 90-degree angles to the direction of the stroke. (In other words, if you paint left to right, the strands will be vertical.)
