Originally planned to use glass beads
and biserins to code them into weeks and days respectively. Just to type linearly and fix them up nicely somehow. In fact, it turned out to be impossible because
the length was too long. Then I started
to think about shapes: flowers (=life), cat’s paws, etc.
But in the end I realised that the best option was to encode months and days, distribute them by years and then by loops of the brooch blank. It worked out evenly:
4 strips of 3 years and 1 day each, with 9 months and 2 days in the middle.
