[1] Karin showed early artistic talent, and after attending the Franska Skolan in Stockholm, studied at the Slöjdskolan (Handicrafts School; now Konstfack) and from 1877 to 1882 at the Royal Swedish Academy of Arts.

In 1888 the Larssons went to Paris, on the suggestion of Pontus Fürstenberg of Gothenburg, who wanted a large painting by Carl to add to his art collection.

They left their two children with Karin's parents in Hallsberg, and upon their return a year later, decorated the Bergöös' new house.

[8] 1997, Victoria and Albert Museum in London showed her interior design at the Carl Larsson exhibition.
