Celebrations in Cashmere

When I was 8 years old, I started a tradition of writing myself a letter on my birthday. Every year after my 15th birthday, I wrote to myself while wearing these ballet pink pajamas that my grandmother gave to me. This year I added a cashmere wrap from a lovely friend and wrote in quill and ink from Signum Firenze. With old age comes decadence.  Do you have any birthday traditions? Does it also involve cashmere?  — in Rome, Italy.
