One of the art pieces you are undoubtedly going to encounter is the Needle, Thread and Knot. Its meaning is tied to the railway services in Milan (when the needle and the thread get inserted into fabric it reminded the creators of a train entering a tunnel) and the fashion influence of Milan. The colours of the thread represent the city's metro lines.
