I'm glad you asked.
And you can read a lot of it if you go to my Minnesota State Fair Round Up page.
There you'll find links to my posts on how to prep for the Fair (what types of painting gear and such to bring) and how to train for the Fair and what to eat when you get there.
Mostly you'll find lots of posts on how to think productively and creatively about what you want to do at the Fair (i.e., what you want to sketch) so you can hit the ground running and fill those journal pages.
So go check out those instructions now.
I am looking forward to seeing ALL of you at the Minnesota State Fair Sketch Out 5 on August 27, 2013!
