 Natural dyes

Tetri Design has been in business since 2003 and has a web shop specialising in natural materials and craft courses.

Behind Tetri Design is Anna-Karoliina Tetri, a professional craftsperson and author, to whom natural materials are not only a business, but a way of life. "In my youth I came across wool in many places, even in the forest, when the scouts were felting mice at orienteering control points. I worked with wool during my studies - with everything from fine wool combined with silk in Japan to sturdy fabrics for the medieval markets. Wool has been my companion for over ten years." In Anna-Karoliina's hands the natural woll dyes beautifully with natural dyes:" To me handcrafts and natural dyes are a profession. I use the most environmentally friendly methods possible during the dyeing processes while still keeping in mind light- and colourfastness. I also want to share this old handcraft and new research information on the topic with my customers."
