To start, have the kids write their name on a canvas with the white crayon and decorate as they please. They can add whatever they like – stars, dots, squiggles, lines etc. Just make sure you press hard enough to leave a good amount of white wax on the canvas. The wax is essential for resisting the watercolours in the next step.
Next dip your brushes into the liquid watercolours, and brush the colour over your canvases. The white wax repels the paint leaving your name and design to show through the colours. When using watercolours you can dilute the strength by adding a few drops of water if you’d like the colours to be less intense. Rinse, and wipe your brush dry when switching colours.The canvas should soak up the watercolours beautifully.
