Art and the Homeschool Convention

I am working to set up the third annual art classes at our Local Homeschool Convention. Time really sneaks up on you, You think you have all the time in the world...and BAM! it's around the corner. The classes for the convention are for elementary age...I also have been planning classes for the Library this summer. Those are teen classes. I pretty much have figured out keep it short and keep moving fast so you don't loose their interest. :) The project I am using for the Convention is a one I used lst summer.."Bamboo at Midnight"...for lack of a better title and fun ....
