Several missions in Starfield require the protagonist to find resources and items to craft more valuable items. One of these resources is fiber, a commonly used item crafting invaluable tools for players through Starfield's story and many side missions. Fiber can be found by harvesting planets rich with plant life or by purchasing it from a variety of vendors throughout the galaxy in Starfield. Thankfully, players won't have to wait long before getting their hands on fiber as it is available very early in the game's story.
