Pete takes you through all of the options, shows you how each option works in concert with the others, how to leverage the built-in tool presets, and how to customize them to make your own brushes. Once you get the hang of the Mixer Brush you’ll find that you can create strokes, details, and looks that you just can’t get any other way.
