[Cob] Hemp in cob

[Georgie Donais]

Cjristos,

I have worked with hemp straw a little bit, and it seemed rather 
unsuitable for cob made by foot. The strands are curly and tend to 
get wrapped up together instead of getting distributed throughout the 
mix. They are also a bit sharp, so not so comfortable for the feet. 
The fibres do appear tough and durable though. And I have used hemp 
hurds in plaster to great effect.
