Illustrator CS4 introduces the new Blob Brush tool to users. Instead of a regular brush stroke, painting with the blog brush gives you a filled, compound path. Any new shape painted with the same color and stroke will automatically merge with existing shapes with the same settings. The new tool will pick up style attributes from other objects and has numerous other options to explore and play around with.
very cool. how can i get it?
Upgrade to CS4
FINALLY!!! Thank you Adobe.
Yellow and Red? Those shapes are orange. Nice tutorial though
haha vector van gogh. oh man adobe never seems to let me down
MMM I love Icecream sandwitches…lol
Hahaha.. those shapes were TOTALLY not yellow.
Its pretty neat how this blobby works. Me likey. 
I love the tutorial, easy to follow and shows good ideas. Thanks.
I loved this tutorial. I’ve been using the blob brush to make vector versions of sketches, but hadn’t realized some details like how to switch tot he smooth tool with the option key or adjusting the brush size with the brackets. Thanks!
Nice. I never paid any attention to this tool before but after seeing this tutorial I’m gonna give it another look.
BTW, Corel Draw had this feature 10 years ago, probably more. Why is Illustrator always so late with stuff?

Best video tutorial on Adobe site, IMHO..
Great “caveats” and exceptions pointed out. Cheryl rules.
I am going to look for other tutorials you did.
Could you please make tutorial on “Bristle Brushes” ?
