So you want to do some work with chalk pastels? Here's a wonderful place to start: 100 Free Art Lessons at Hodgepodge - Art for All Ages (Chalk Pastels & Acrylics) Plenty of helpful techniques, links to tutorials and, projects/lessons!
Could this be turned into a display for student work at school? Hang clipboards by those hooks that you can take off easily? Clipboards on the wall to display kids art. Could be really cute with scrapbook paper decoupaged on clipboards
