Since the 1990s, Guillaume Dégé has been devoting himself to keeping notebooks, this daily practice becoming the breeding ground for all his graphic work. In this talk, Dégé presents the typology of his notebook practice, both free and without prerequisites yet also ritualised and formalised. A bibliophile, Dégé details the uses of the notebook as an intimate tool with examples ranging from ‘jogging’ notebooks, which allow him to formulate graphic problems while maintaining his hand’s ability, to ‘compost’ notebooks, where interesting parts of failed drawings are recycled through collage.
