35 Abstract Illustrator Brushes

In my opinion, one of the most underused features of Illustrator is the creation of custom brushes. You can literally make ANY shape into an Illustrator brush to get all kinds of cool effects. I put together a set of 35 abstract brushes for you to play with. The example below was made only with the brushes I provided in the set, and I only used 3 shapes: Mostly circles, a couple starbursts, and a spiral or two. Every bitt of detail in the example is created from the brush strokes alone, on different sized shapes/stroke sizes
