I've posted a number of brushes suitable for use with Adobe Illustrator (multiple versions) on my blog. I'll repost the links here, in case it's easier to see them all in one place. (Right click to download).

 

 

Downloadable Illustrator Brushes

• Railroad Track Brush
• Rope Brush
• Candy Cane Brush
• Filmstrip Brush

More to come (no doubt).

This Illustrator brush is totally free, but if you found it really useful, I wouldn't argue if you wanted to send me a dollar. No pressure though, it's totally free, and I'd likely waste the dollar anyways.
