Ainu people (indigenous to Japan) use long wood shavings as a material to weave or braid into headpieces. The movie Ainu Mosir includes a scene that demonstrates the process of shaving down a green stave with a sharp knife. The stave was about .5 meter long and the shavings stayed full length. When they were later braided/woven, they made a strong material.
What properties would make a wood suitable for this task? Does anyone know what wood the Ainu use? I know they use elm to make clothes, so this could be elm as well. I am also looking for any potential temperate alternatives.
