There are lots of brushes you can buy online and load into your Brushes Palette, but it's easy to make your own. In this tutorial we will make a bicycle chain graphic and turn it into a brush to be used as a stroke. This is not difficult but there are more steps and key commands in this one. I hope it will help make you familiar with the Blend Tool, The Pathfinder, and a great little pencil called the Smooth Tool. Enjoy creating your custom bicycle chain.
