I always have examples--either mine or students. And sometimes stages
if it will help them.
I also work on the projects during class with them if time allows, too.
I have even worked on a high school project during the middle school's
studio time and found students very interested. I always would tell
them, "I need ya'll (southern term) to work on your projects and let me
work on mine, too!" Usually, they are positive with their responses. I
encourage students to display their ongoing projects in a designated
area--it helps others to see "how to" and gives a boost to the ego!
High School students especially like to hear about others looking at
their work! I fimd that the more I can show students' artwork, the

"Wall-Of-Fame". This is a favorite for everyone! I take a picture of
each class with my digital camera, and then each student draws a full
