Arango held her first individual exhibition of paintings in Medellín in 1957 in a space in Casa Mariana. On the second day, Arango decided to withdraw her works due to the fear caused by the demonstrations against General Rojas Pinilla. In 1959, she traveled to Europe for the second time and in England studied ceramics at Reading Technical College. In the 1960s, Arango decided not to show her works again, having received threats and pressure from her family. Then began a long period of isolation during which she decided to intervene pictorially in La Casablanca, her house-workshop in Envigado.
