5 Tips For The Illustrator Brush Engine
There are probably lots of ways to use the Illustrator Brush Engine to make life easier, I just wanted to point out 10. I would like to credit Veerle and her post about Brushes which indirectly prompted me to think about this.
The swirly curls from Veerle, could be accomplished with a single curl and the application of a brush like this. Note the simple variations that yield impressive results.
I love the Art Brush Setting, but what I love even more is the Pattern setting. Use it too make a Celtic/Greek Key pattern like this. Not that simple, but super powerful. If you want the corner and end pieces, you need to add the object to the swatch palette.
