The Sustainable Colour exhibition at Design Museum closed last month. Before closing we organized two guided tours for science, home education and crafts teachers. Elina Batterbee from the museum streamed the tour for on-line participants while Riikka Räisänen explained the history, present and future of sustainable colours in detail. Sanna Siekki and Josefiina Vanne, who are part of the BioColour project, hosted a workshop for both on-line and f2f participants. A lively discussion on how to incorporate sustainable colours in teaching resulted in new and colourful ideas!
