Sigrún was described as a fun-loving woman. She  took care of social issues, in particular she was concerned about the home industry and women's access to good and diverse education. She gave inspiring lectures and was considered a great orator.

Sigrún was the leader of the school together with her husband Benedikt Blöndal. She had a high regard for handcrafts and practical knowledge, but also emphasized academic learning in culture, languages and science. A large collection of books, both foreign and domestic, found their way onto the shelves of the school building, and Sigrún was diligent in translating and composing new teaching materials.

The new study program in sustainability and creativity draws inspiration from Sigrún's ideals and her works and interweaves them with the pressing issues of our time.
