Flax is a bundle of fibers harvested from only one plant: the flax bush.
Appearance
Flax is a narrow shaft of dark green laying at an angle. It appears to flare at either end.
Where Found
The only source of flax is a flax bush. Only the lower half of the bush will produce flax, and even then, only when mature. If harvested with a machete or spade, a flax bush will produce three pieces of flax instead of one.
Crafting
Flax can be used to craft a tailor's bench, which can be used to craft clothing.
