Stained glass is a medium unlike any other. Its interplay of light, colour, and form is endlessly fascinating — and endlessly generous. Glass can be literally filled with light in a way no other material can, and it is that quality I return to again and again: the ability to create whole environments, to tell stories not just on a surface but through it, in colour and light that shifts and breathes with the day.

I work from my studio in West Wales, and after twenty-five years I remain as captivated by this material as ever.
