Step 7: Paint
Colour in the design using the black paint and the sharpie. Use the sharpie for the fine detail and the craft/hobby paint for the larger areas. Use a pencil, inserted into the hole in the bottom of the egg to help you hold the egg while painting.
For one of the eggs I left most of the egg orange and did the face in black.
The egg with the ghost, I painted most of the egg black and left areas unpainted for the light to shine through, with this egg I did not bother dye the egg orange beforehand, I thought it would look okay without it.
You may require several coats to make the black completely opaque (using several coats of paint also helps make the egg harder, less fragile.)
