Saara Renvall works on a wide variety of design projects as a freelancer in her own design studio called Studio Sunnuntai and in groups with other designers. Her works vary from basic furniture design towards more artistic projects. She is one of the co-founders and organizers of Imu Design - Finland's self-appointed National Design Team, representing young Finnish designers.

Surprises are a big part of Saara's designs; she likes to try out different materials. When asked about her favorites she replies that like a cook that doesn't want to do everything using only potatoes, she also likes to make desserts, main courses and sweets. "You have to have the idea and use the material to realize it, not vice versa". Saara loves Sundays, licorice and maps.
