These whale crayon etchings were made recently by a class of grade 3s. We made our own 'Scratch-LIte' paper rather than buying the plastic sheets. If you haven't done this before and would like to try it, all you need to do is cover a page entirely using coloured oil pastels or crayons and then paint the page with a coat of black paint (student acrylic works fine). Once dry we used nails and wooden skewers to draw into the black paint, revealing the colours the students used underneath. If you stick these up on windows they look amazing with the light glowing through the colours.
