My online class "Keys to Dynamic Composition" starting in October is full full full. Really full. I keep getting inquiries about it, and hate saying "no", so I am offering it again starting in March. Check it out and sign up early if you are interested. This will run concurrent with Sketchbook Practice. I don't advise taking both unless you have considerable time to dedicate to it. Which you may have!

And just because I mentioned Dean Nimmer above, he has a new book coming out this fall called "Creating Abstract Art". I'll be doing a giveaway of this book when it's available.
