Fuzzy blender. Ideal for making clouds and other soft blended textures like spreading ink or furs.
The strokes will blend directionally, for best effect and fluffy clouds, go in various directions! The angle isn't randomized to give better control as to the shape you like, but in every direction, the fuzz will go outward.
The more times you go over it, the softer it will be! Very strong effect in just a few strokes.
