Harri Koskinen designed the Frekvenssi (frequency) fabric in 2006. The print formed part of the Marimekko spring collection in 2007. The motif, crisp and largely graphic, taken from the name of the collection, gave a completely new look to Marimekko design. Th abstract motifs, shapes and lines develop into cause and effect systems, while the different colour shades are able to satisfy a variety of settings. Four Frekvenssi Trevira CS are available, along with a Frekvenssi for upholstery.
