Reverse Engineering a Graphic Style

One of the best ways to learn all the great things you can do with graphic styles is to apply an existing style and then check out the Appearance palette (Window>Appearance). The entire makeup of the style will be laid out nicely for you extra fills and strokes, effects, colors, and so on. In addition, if you really like a style and want to make a new one based on an existing style, you can of course, alter the style by selecting it in the Graphic Styles palette and changing style items in the Appearance palette. Then just click the New Graphic Style icon at the bottom of the Graphic Styles palette.
