The collaboration between Oleana and the designer Solveig Hisdal started late in the autumn of 1992. Subsequently, all Oleana's new designs have been created by her.
Solveig Hisdal also photographs all the models and is often involved in the lay-out of catalogues and posters.
Solveig Hisdal's background is in graphic design, art and fashion design. In 1995 she won the "Scheiblers Honorary Award". From the Norwegian Design Council, she and Oleana have received the award for Design Excellence six times.
In 2000 she was awarded the highly coveted Jacob Prize – Norway's most prestigious award for design, crafts and architecture.
Solveig Hisdal is regarded as one of the best textile designers in Norway, and her signature is clearly visible in the Oleana collection, through her colourful and well-developed sense of ornamentation and shape.
