Paint some glue onto the egg and then place a tissue paper square over it. Paint some more glue over the paper and repeat until the egg is covered.
My Daughter didn't like touching the glue, so I cut a hole in this left over plastic bowl from my son's birthday party. She was much happier. She made 3 eggs and here they are in my corn on the cob holder that I painted white and distressed. I got it at Goodwill for 50cents and I kind of wish I bought more than one ):
