Caroline attended Hornsey College of Art and served a stained glass apprenticeship under her father Carl Edwards FMGP for whom she worked at the Fulham Glass House where she painted his design for the Great West Window of Liverpool Anglican Cathedral and cut and painted a window for Washington Anglican Cathedral designed by Rowan Lecompte. In 1990 she opened her own studio with her husband Tony. Caroline designed and Tony painted the windows applying Arts and Crafts principles to contemporary design.
She believed her studio is a place where adventures in colour and transmitted light can take place through experimentation with glass, glass paint and a variety of processes while remembering the architectural context in which the completed windows are fixed. Making new glass for either ancient or modern buildings, she worked closely with her clients to produce a working brief and to complete commissions that appeared as though they have always been in place and not shouting at the other glazing or decoration.
Caroline was active within the Society for many years and was Chairman of the Council for over twenty years. She worked tirelessly to promote stained glass as an important public art form as well as a craft and to introduce its rich and fascinating history to a wider world.
