Fiber is the first processed step after collecting Fibrous Pulp. Keeping a few pieces ready supports both swimming equipment and healing supplies without requiring a separate deep-resource trip.

Quick answer: Make 1 Fiber from 2 Fibrous Pulp at the Fabricator. Fiber is used directly in Basic Fins and first aid kits, or combined with Strong Acid to make Fiber Mesh.
