She won the first two Gold Medals awarded by the National Eisteddfod of Wales in the Fine Art category, for her paintings Girl with a Siamese Cat (1951) and The Cristin Children (1953), and her written works include Tide-race, a memoir of 15 years spent living on Bardsey Island. An expatriate on the island of Hydra, Greece, from 1961 to 1967, she then returned to Wales, where she died in 1971. Her papers are preserved by the National Library of Wales; examples of her artworks are found in several collections.

In 1931, Chamberlain began her studies as an artist at the Royal Academy Schools in London.^[2]

Chamberlain ran the Caseg Press in Bethesda, Wales, with her then-husband the artist John Petts, and the poet Alun Lewis.^[3] The collective produced postcards and bookplates, for which Chamberlain made woodcuts.
