[2] She later took up art as a hobby, and was effectively self-taught, yet her works commanded reasonable fees.
[2] Her obituary, which appeared in The Newcastle Weekly Chronicle on 14 January, praised her artistic merits and social contribution:Miss Mawson who was educated at Bedford College, London, at a time when higher education for women was very rare, was an extremely able artist, three of her paintings being hung in the Royal Academy.
She was also an energetic social worker, holding official positions in the Gateshead Women's Liberal Association, the British Women's Temperance Association, the Royal Albert Asylum, and a large number of peace societies.
She produced landscapes, flowers, portraits, and genre studies, in oils and watercolours.
She continued to exhibit locally, occasionally sending works to the Bewick Club, Newcastle.
