Mari Thomas Jewellery Gallery and Workshop has been based in Llandeilo, South Wales for nearly 12 years. It is a long way from the little workshop at the bottom of her parents garden where she set up 27 years ago but Llandeilo has well and truly become her home since she purchased the gorgeous three-storey Georgian building that was the Old Castle Hotel. It has transitioned beautifully into its current destination venue.
