I found this really helpful tutorial on swirls for Illustrator. I'm working on a flyer for a client. It's a garden mixer so I'm looking for ways to create vines and other organic forms. They will be used as graphic elements to supplement the garden theme. Click on the link below the image to visit the tutorial.

Here's another site I found with some brush presets. These are FREE!
