Wallpaper has initiated a collaboration between Alexandra Jefford, a Swiss designer based in London, and the English firm Smythson, which specializes in leather. Her idea: using links of color, to make 6 knots belonging to different civilizations. We find a Celtic knot, the knot adorning the handle of a samurai sword, a quipu which, in the absence of writing, was used by the Incas as a unit of account, or an Isis knot as seen in the tomb of Tutankhamun. Alexandra Jefford is skilled at creating deconstructed blends based on geometric shapes and materials, and integrates them ingeniously with her gold rings.
