A fuzzy brush for adding texture to fur, clothes, etc.
One side of the brush is straight while the other is fuzzy. To make the fuzz face upwards, move brush from left to right. To make the fuzz face downwards, move brush from right to left.
To make fuzzy circles, move brush in circular motion at the center of where you want the circle. This makes for great sea urchins.
IMPORTANT NOTE: when attempting to move in a circular shape, the start of the line may be slightly distorted as seen above.
