As suggested by their names, the objects of the BOSCO and PISTILLI series acquire their maximum expressiveness in groups, playing with different heights and/or colours, just as in nature.‎ Not only through the technique of paper clay, but also with the infinite compositional possibilities, BOSCO and PISTILLI are regarded as a logical evolution of the Cartocci collection, with which Paola Paronetto has always explored the compositional power of individual objects, united in evocative groups of still life.‎
