This project has been on my to-do list for a long time. I originally saw the idea at Little Humbugs.
Here’s how you make these beautiful-looking decorated rocks.
Go out and hunt for some rocks. Flat ones are easier to draw on later.
Put the rocks in a 230 deg C oven for 15 minutes.
Decorate the hot rocks with crayon. The heat in the rocks will melt the crayon onto the rock. B made the circle effect rocks. J made very colourful rocks by covering the whole surface of the rock with one colour and then beginning the next colour on top of the last.
The rocks are very hot and hold the heat for a long time, so make sure your children understand that they can’t touch the rocks at any time. I put the rocks on a folded towel so they wouldn’t move around.
