To grow hemp for a fibre crop you need to apply for a Home Office licence. It's not worth the bother.........there are enough nutcases out there who refuse to believe it's a fibre crop and the fields get raided........according to a farmer in Ayrshire who gave up trying.
It's a very, very good fibre, and it can be a beautiful cloth.
I met a Magyar(Romanian/Hungarian minority in the wrong country, never did get it straight, Sandbender might know
) lady who grew, processed spun and wove her own hemp. It was graded in three qualities, coarse, everyday and fine.
The coarse was like our heavy slightly noiled linen cloth of a weight like denim. The everyday was like linen teatowels and the fine was like fine sheeting. It was superb
She was as fascinated by my fine Scottish wools though, she didn't believe that wool was strong enough to be spun on a drop spindle, let alone fine enough to weave tartans. I could happily have spent hours talking with her
I ended up with some of her spun hemp and she went away with half of a St.Kilda fleece
Chiseller if you rett that down, it should give you bast fibres, but I don't 'think' they'd do for an arrow firing bowstring, but they should make good rope
It makes good cordage just stripped free of the outer bark anyway
It's excellent for weaving, especially stuff like chair/stool seats, though someone said they'd used it for snowshoes too. Happy to be proven wrong on the bowstring though
cheers,
