I'm at my yearly conference for art teachers. There are always plenty of fun, motivating and exciting sessions to choose from. The first one that I attended was for a community service project called "Love Luggage." This session was led by Sarah Philip of the Congressional Schools of VA.
I found a site on the web that gives detailed directions on how to clean and paint one of these.
The presenter said that one of the only problems with this project is that the student artists had a hard time parting with these treasures.
