Stop by the Clay Center’s POP UP Exhibit Ephemeral Thoughts: An Interactive Drawing Experience at Uncork & Created during ArtWalk. Thoughts are fleeting and often not sacred even though we all want to be heard. Examine the prompts and create your response in the form of a drawing. Will you find a clean area to create your images? Will you draw with someone’s creation as though in conversation? Or will you ignore someone’s thought by drawing over theirs?
