While holding the egg with a kitchen mitt or a pot holder, press the tip of a crayon onto the egg. The crayon will melt as it touches the hot surface. Tilt the egg to let the melted wax run and spread on the egg's surface.
Move the crayon to another spot on the egg, then do the same thing—press the crayon's tip on the egg then tilt the egg at an angle to let the wax run.
Instead of making abstract patterns on your Easter eggs, you can also draw images on the eggs using melted crayons.
While the egg is still hot, cover the egg with a single color of melted crayon. This provides a colored background for the images or designs you want to draw.
When the background layer of wax is starting to set (the egg should be still warm but not hot at this point), draw the image or design you have in mind. In order to successfully make a detailed design, the egg must be warm enough to melt the wax, but not too hot that the wax runs uncontrollably.
