Itadori pulp


White Leaf Paper is pleased to announce that we have succeeded in producing a beautiful, refined, white paper pulp from Japanese knotweed (Fallopia japonica), called Itadori in its native Japan, which produces a white paper full of character and life. Knotweed is a notoriously invasive plant which requires lye solution and extensive Hollander beating for  hand papermaking, producing a brown or tan paper. Until now.

We are making this pulp available

to hobby and artist hand papermakers.

When we make paper solely from this pulp, it produces a

lovely paper, often with some visible fibers,

that is smooth, translucent, rattly and brittle.
