In 1944, because of wartime yarn shortages in Finland, she moved to Sweden and designed shaggy rugs for Textiles & Interiors in Stockholm.

A year later she took a post at the NK Textile Studio, where she began to design patterns for textiles and made a reputation for her colourful geometric designs.

In 1956 she became artistic director of fashion textiles at Mölnlycke Weavers, where she stayed until her retirement in 1973.
