The exhibition, curated by Valia Barriello, was born from the will to highlight one of the aspects of production which is rarely talked about, the obstacle. The problems which occur during the realization of an object often lead the designer to an unexpected or optimal solution. The visitor will find out some hidden aspects of self-production and even some funny anecdotes, and the exhibition will become a story telling about obstacles, solutions and a peculiarity of every good designer: stubbornness. Through broken prototypes, shapes, chalk moulds, distances, calculations and artisans’ addresses, the exhibition wants to tell all the difficulties, sometimes objective, sometimes subjective, which the designer had to face.
