Stoff is a web portal dedicated to publish educational models and best practices for art and music teachers. The portal is maintained by Tölö Gymnasium and the project is part of the Ministry of Education and Culture's National Development Task.

The logotype draws its inspiration from the cracked surface of lava stone. It was designed in collaboration with Double Happiness.

Stoff’s visual look is not tied to time or place and is based on three values - quality, transparency and good practice. These were also the driving force in creating the experience.
