Fiber Dictionary (with pictures)

Understanding fibers is the first step to mastering textiles. 

But with a countless list of things to learn, diving into the world of fibers can be overwhelming. 

That’s why I made this Fiber Dictionary – to serve as your quick reference when learning the fibers that shape fashion. I also made sure to include some pictures to help you remember them!

So, whether you’re a fashion student, a freelance fashion designer, or an in-house designer eager to understand the basics, this guide is your ticket to all the must know fibers used in textiles. 

Let’s start!

Why am I qualified to write about this stuff? In my 15 years of experience in the fashion industry, I’ve journeyed from being an in-house designer, starting my own brand (yep!), to growing my freelance career to $100,000+. Now, with all the knowledge I’ve learned along the way, I want to help fashion designers (and PDs, TDs, etc.) like you make it in the industry.
