The Les Garçons British 4-Ply base is a fingering-weight yarn spun from a beautiful blend of bluefaced leicester wool and natural brown masham wool. Mashams have been bred for over a century on the hills of Northern England. When dyed, amazing and deep colours come through due to the brown masham fibres in the blend.

The Dyed by Delz Yak Sock base is a blend of 20% yak fibres with 70% superwash merino wool and 10% nylon. The raw fibre base colour is not white or ecru, as other undyed yarns are. The dark yak fibre lends depth to the base and the dyed colour.
