In 1966 the Amarals were invited by Miguel Arroyo to show their work at the Fine Arts Museum in Caracas, Venezuela. It was the first solo show by Olga de Amaral outside her native country. In 1967 Olga presented her work for the first time at the prominent Lausanne Biennale in Switzerland, the first out of six later appearances at that event. In 1969 Olga de Amaral took part in a collective exhibition of 27 fiber artists at MoMA New York entitled “Wall Hangings”."Olga de Amaral in MoMA Exhibitions", Museum of Modern Art, Retrieved 17 November 2018. It was an international exhibition curated by an architecture and design curator Mildred Constantine organised with Jack Lenor Larsen and presented not in the architecture and design lobby as usual for the fiber artists, but in the art section of MoMA, that up until then was reserved only for painting or sculpture. This was the importance of that exhibition - it addressed the transformations in the medium of fiber art, noted differences between the continents and anticipated the experimentation to come.
