At artstream, we use a lot of recycled objects as well as bonafide art materials to create with. Here is an easy reuse of the freebie foam core which most frame shops throw away. Go ask for some at your local shop. They will be happy to see you!
To make these mask/faces we sorted the bits into a few bins of small, medium and large shapes. For the actual “head” we had the children draw on a larger piece and we cut out that shape for them with adult size scissors. They glued on the features and used wooden skewers and toothpicks for hair. The foamcore board accepts the skewers easily on the edges as it comes with premade hole like formations. Paint, markers, or inks could be used to add color, as well as beads, ribbons and yarns added to the “hair”. Everything was glued on with a white glue although if you were in a hurry to finish, an adult could use hot glue. More photos of this process right here at flickr.
