One little game she had us play was to rewrite our artist statements in a Twitter format. 140 characters or less. This will give you a concise statement about what you do, so that when you meet someone at a party or wherever, and they ask you what you do, you can easily tell them! This is your one-liner. Memorize it. Make it good, make it pop. Needless to say, I'm still revising mine :)
She gave us samples of her different promotional cards and materials; fun stuff to see. I'm pretty sure that all visual artists enjoy colorful, attractive cards.
So, if you get anything like this in your area, it's worth it to spend a day in one of the these classes. Even if you think you know everything already, there's always something to be learned. Thank you, Didi!
