I have developed an entirely handmade process to create the Herringbone objects.
I begin by drawing a mathematically complex pattern which represents a flattened version of the object's final 3D shape. I then overlay a sheet of thin transparent plastic sheet which I score and fold according to the pattern underneath. This produces the 3D 'Herringbone' origami-like relief. I then cast resin directly onto this folded sheet. While the resin is setting, and malleable, I manipulate it into its final vase shape. I then have the 'master', which is then used to create a set of moulds.
These moulds capture the form of the master with near perfection. It's into these moulds I cast each herringbone object.
