To obtain fiber, in New World you need to harvest it from the hemp plant. Hemp plants are found throughout the two biomes of Aeturnum: forest and grassland. Hemp plants are tall plants with purple flowers on the top of each stem. To harvest fiber from the hemp plant, you need some kind of harvest sickle.
Fortunately, it is very easy to make one-all you need to make one on a campfire is 1 green wood and 1 flint, and you can collect them in the starting area around Monarch’s Bluffs Watchtower.
Fiber is another useful crafting resource, and you can make it into fabrics for clothing and armor perfectly. It is also used to make your first wooden fishing rod.
