In May 2009 Cecilia started to work on a large scale art project in Swedens second largest prison, Kumlaanstalten. The work consists of a more than 200 meters long wall decoration made in cooperation with the male prisoners. The wall was newly rebuilt and the original wall decorations made in the seventies was lost, now Cecilia works with small groups of prisoners to create new decorations for this seemingly endless corridor.
The wall is covered in steel sheets which are being worked upon, with a lot of different techniques.
