Blow's work was widely exhibited during her lifetime. Notable exhibitions of her work include sales made to the Museum of Modern Art and the Tate Gallery, the 1958 Venice Biennale, the 1960 Guggenheim International Award (which she won), the 1961 Liverpool John Moores University exhibition and at the Victoria and Albert Museum. Despite moving to St Ives in the 1990s, Blow continued working in London, participating in the Royal Academy's Summer Exhibitions and being honoured with a retrospective in the newly completed Sackler Galleries in 1994. In 1995, she completed her "only large scale experimentation with glass", an illuminated glass screen named "Flight Structure", which was installed in Terminal 3 of Heathrow Airport. This was installed by the airside entrance and the artist styled the work to convey the transition from security to flight. It has now been moved to the airport's head office in the Compass Centre. In 2001-2002, "Space and Matter", became the title of an exhibition of Blow's work at Tate St Ives.
