Many people believe that hemp and linen are the same material because they are both obtained from the stem of a plant and because the fabrics made from these fibres tend to be very similar in appearance. Besides the fact that both plants develop extraordinarily long fibres, the main differences are that flax has a much rougher surface than hemp and that flax comes mostly in different grey tones, while hemp fibre usually has brownish tones ranging from blonde to dark brown or almost black.
