The Bjork rug is based on a weft in wool, combined with details in leather. The expression in the woven structure is inspired by the black and white trunk of the birch tree (‘Björk’ in Swedish) and the leather represents the inside of the bark. The marbled effect in the colour of Björk is created through intertwining different coloured wool yarns in the weft. Wool is known not only for its softness, but also for its built-in resistance to soiling thanks to its natural oils. Björk is woven by hand and as such is a piece of craft and therefore the appearance can differ from product to product.
