Here is a vector session from start to semi finish.  Started with a rough sketch to final vectoring.  Everything is done by mouse and pen tool with the assistance of pathfinder, a custom pattern brush here and there and lots of hoping that Illustrator wouldn't crash.  Hope you enjoy!

Prep for stickers through Stickerobot.com

Print mock up. dunno if i'll do it. but worth a mock at least.
