In 1962 Wynne-Jones bought Trevaylor House near Penzance and provided accommodation for other artists including renowned Irish painter Tony O'Malley, sculptor Conor Fallon and English poet and writer W. S. 'Sydney' Graham. In the 1970s she exhibited in Ireland; at the Project Arts Centre, Dublin (1970) and at the Emmet Gallery, Dublin (1975 and 1977). During the 1980s Wynne-Jones exhibited at the Lincoln and Hendricks galleries in Dublin; before joining the Taylor Gallery, run by John and Patrick Taylor. She was elected honorary member of the RHA in 1994 and became a member of Aosdána in 1996. Originally an abstract artist, her contact with the Irish countryside slowly transformed her work to that of a landscape artist, albeit with an influence of abstraction attached to it. She became well known in Irish art circles as an eminent Irish landscape artist.
