Regarding Liguid Starch: Laura, You can use the starch as a meduim for
marbling with diluted acrylic paints. You ned to put about an inch of starch
in a flat pan, drip the diluted paint onto the surface, swirl the paint, etc
lay paper lightly on the surface, lift up gently, rinse off the starch under
the faucet with gently flowing water and let the paper dry face up. You will
need to practice this before doing it with the kids. Works great with grades
5 and above.
