❝The word curiosity immediately triggers in me a desire to explore places, disciplines, industrial and craft sectors of the present, but also of the distant past. This provides food for the mind and spirit, which can give rise to highly innovative ideas with a significant socio-cultural, artistic, and functional impact. The world of leather, the first material used by man, stimulates great curiosity because it allows us to travel back in time to every corner of the world.❞ — Alessandra Siena on "Curiosity"
