To make a long story short: this hat is the answer to a very specific request and, at the same time, a knitted way to dispel a legend - my omen to see the rain falling down inside the Pantheon (full story inside!).

A fitted and very elastic beanie, textured by ribs resembling the wonderful coffered dome, it is worked in the round and seamless.

Pattern provides written instructions as well as charts and schematics.
