After her structured training at Saint Martin's, Blow was influenced by Nicolas Carone and his approach to colour and space. He in turn had been influenced by Hans Hofmann. Blow was also influenced by Alberto Burri, who was progressing towards abstract art informel, using materials such as sacking. Blow and Burri started a relationship, and travelled together throughout Italy during 1948, influencing each other's styles. It was through him that she started to use "poor" non-art materials, as seen in her painting "Space And Matter" in which she used liquid cement plus chaff and charcoal, but his lasting influence was in his commitment to art and his interest in the different textures of the world.
