This activity teaches sustained mark-making and the surprise of repetition as a method. The student practises one mark over and over on paper, then transfers the discipline onto a three-dimensional object. The page is the rehearsal. The object is the payoff. The fifteen-minute timer matters. Students will want to stop early because their hand gets tired. That tiredness is part of the work. Pure repetition produces something the student could not have planned. The transfer to an object turns the practice into a kept artwork.
