This would not likely have produced very good paper. Kozo and gampi have
very long, soft fibres which are easily prepared by hand beating. True Hemp,
like flax, can only produce well-bonded, smooth paper when beaten with a
Hollander beater (and a sturdy one, at that).

I was sort of under the impression that "hemp rope" was made from manila
hemp. The "hemp" rope I've seen up close certainly looked more like the raw
Abaca fibre we sell than the raw hemp fibre we sell.

>Has anyone on the list actually made paper using just hemp?
Yes. We have a stock of Ontario-grown hemp (from the colour it looks like it
was dew-retted) from which we have made a batch of paper. We also have some
imported (from Spain, I believe) hemp half-stuff intended for papermaking.

How about: Wood pulp is cheaper at the industrial level? Hemp fibre is
harder to prepare than most other fibres for the hand papermaker? The DEA
hates hemp in any form?

There is no problem bonding hemp fibres. The alkaline cooking and beating
processes will destroy any non-fibrous cells.
The "picking" process used to clean Kozo is removing visible dark particles
(usually bits of outer bark that result from knots and side branches on the
original plant) which would deface the finished paper, not to improve
