I had a class with five adult students recently and they did great! In two hours I was able to touch on the history of pysanky, how to empty an egg, and the basics of an 8 pointed star design. It was a great group and once they had the basics down, I let them go wild with the colors.
This is a great thing to do with friends or even at a party. Feel free to contact me using the contact page if you'd like a class for you and your friends!
