A quote from
SWICO Ag on the Internet.
"Clothing made from stinging-nettle fiber is about to hit the catwalk and an Italian fashion house has started to produce a range of nettle jeans and jackets. Before long nettle knickers may be all the rage, and supermodels such as Kate Moss might be spotted sauntering down the street in a nettle-fiber dress.
... Nettles made a brief comeback during the First World War, when Germany suffered a shortage of cotton and nettles were used to produce German army uniforms.
... The fibers of the stinging nettle have a special characteristic in the fact that they are hollow which means they can accumulate air inside thus creating a natural insulation.
