Linen

Linen is a very durable, strong fabric. The fibres are resistant to damage
from abrasion. Linen is made of flax. Flax is a food and fibre crop cultivated
in the cooler regions of the world.

It's a bast fibre obtained from the stalk of the plant and the second
most important fibre in the textile production. It's termed 'linen' once
it is spun into a yarn and woven or knitted into a fabric.
