Patrizia's idea of a piece of "wall on the wall" uses the recycled materials "from the street", such as truck tarpaulins, pieces of jute, fabric, paper or cardboard, are overlaid with "15 to 20, sometimes more" layers of painting, consisting of a mortar-gypsum mixture enriched with pigments. In the process, Casagranda makes use of the artistic range that graffiti has to offer. Stencils, grids, sprayed and painted areas are found next to and on top of each other, also in combination with type fragments that she takes from different contexts. These can be a poem or Charlie Chaplin's speech from the film The Great Dictator. While not originating from this scene, Casagranda's use of graffiti techniques demonstrates how this artistic counter-movement has managed to reach the art world's mainstream.
