I know Wendy will give you an answer, too - but I know
hers are watercolors over the finished scratch board.
I have done the method you mentioned with grades as
young as 1st grade - and as old as high school. The
trick is NOT to have the ink too black. Add a bit of
dish detergent (but not too much as it will penetrate
the crayon) and just a bit of water (you will have to
experiment - I always tested the ink mix before having
kids use it). My second graders made the most gorgeous
fish compositions! I wish I had digital images of
those (from 1990 - pre technology for me).
