This home-grown, feel good fabric has been used in the textile industry for centuries. Grown at Huit Farm in Leicestershire (under a government licence). Hemp is a wonderfully sustainable, fast growing plant; only 45 kg of hemp seed can make up to 5,400 metres of fabric... that's approximately 300 pairs of curtains for one bag of seeds! And the production waste? What production waste? Any waste fibre is decomposed and used as fertiliser for the following year's crop.
