A stencil painter and teacher, Samuel Idmtal lives and works in Brussels. His practice is primarily centred around participative frescoes. He tries to involve the residents of the area where the murals are located as much as possible, by involving them directly in the creative process of the fresco (brainstorming on the model, taking photos, assembling and cutting out stencils, introduction to spray painting on the wall itself) so as to leave a communal work that will appeal above all to the people who see the fresco every day.
