There are two ways to approach a name commission; one is to start with the name and find some history, meaning or aesthetic in it that inspires the rest of the piece.
Another is to start with the shape of the letters, find a font that seems to make the shape sing and then see if that suggests the next step.
This commission was definitely the latter approach, I felt really stuck with it until I hit upon a rather lovely font which then instantly suggested the Book of Kells.
After that, it was just a case of finding my most jewel-like colours and setting to work!
