Professional development at Artsight in Auckland. They have a venue in Wellington too. I arrived late as Wellington airport had crazy fog and my flight was cancelled. I was generously offered the opportunity to attend another session later as I missed half of the day. What I did experience was valuable. This charcoal drawing is on brown paper which offers a mid tone. The addition of white paint is another tone and using an eraser, another. Added pieces of paper add interest. We worked standing, on large sheets of paper. If space allowed, it would be a great experience for children.
