Screen printing with Modge Podge - how clever - the screen chemicals are so expensive. This is a great idea for art center. We already have the screens, modge podge and inks - we would just need to reclaim the old screens.
craft idea for kids- monster pet rocks. Pre-paint rocks and they can draw faces. I have a lot of googly eyes I can bring in. This can be a cheap project. Maybe high school kids can paint the rocks. Maybe use half Easter eggs if short on rocks?
