The website Vector Boom is an outstanding resource for Illustrator tutorials and tips.
Here, Natalie Ulrich has a tutorial series,
“Effective Methods of Working in Adobe Illustrator”
(8 in total), ranging from how to use the very basic tools to the more advanced. She is very detailed in her instruction, and has many picture references. A wonderful reference for the learning novice, or the professional who just needs a little reminder.
