I was sharing information with a client this weekend. He wanted to know how to make and control a paint brush in Adobe Illustrator. It´s lot of fun, but not at all intuitive in the Adobe Illustrator application. We had fun with it. I shared with him how to get the the hundreds of brushes in the Adobe Illustrator Brush Panel, modify them, and save them to his own liking.
I also referred him to this collection of free Adobe Illustrator brushes from Design Mag. I hope others will enjoy this collection. See the Source for Free Adobe Illustrator Brushes.
