Another great tutorial. This was something a little different and lends itself to lettering and other shapes. This is from Nobu Design and is called Illustrator Trick: Art Brush Lettering.
Once you’ve created the art brush, use it on any path you want.
I found that it worked better if I broke the path on some letters so that the two ends of the brush didn’t munge together and remained distinct and separate.
When life’s too short to stuff a mushroom these quick effects are wicked little go-to brushes.
