Moko A.K.A Maori Tatto's ( Social Stidies)

In Social Studies we are learning about  Maori Europeans and we are focusing on the topic of Moko ( Maori Tatto's) I learned that the left side of the face means it's the mother side and the right is the fathers. The most confused bit of the whole this is the drawing part. I also learnt to be able to have a face tattoo back then you have to be strong. (I don't know why I do ghoul eyes)
