Halloween plates decorated with food colouring

Getting into the halloween mood.   A really simple non permanent way of decorating plates, we used a food colouring pen to decorate some plates.

We drew a spiders web and ghost eyes, but the possibilities are endless...blood, fangs, green goo....


Its edible obviously, so it doesnt matter if it rubs off on the food, and washes away so you dont need to use (and store more crockery).
