DIY Mini menagerie. Frame. Spray paint, animals, card stock, and hot glue. I just donated so many of these little animals last week! With a new baby in the house, I'd want this in a shadow box to make them less tempting chew toys!
Easy abstract painting that anyone can do! Just blob the paint on the canvas in random spots and blend! (would be interesting how students could make different pictures w/ the same colors and same blob positions)
Spray painted dollar stor plastic animals. A sexy decor item - these could also be used as drawer pulls. May not stand up to heavy use, but for a light duty or occassional use item they would look great.
