If you’ve ever owned a baseball cap, snapback, or fitted hat, you’ve noticed the small, round button stitched right on top. It’s such a tiny detail that most people don’t think twice about it. But have you ever stopped to wonder: why is it there?
The answer is more interesting than you might expect.
🧵 1. The Original Purpose
Back when baseball caps first became popular in the mid-1800s, hats were constructed from several triangular fabric panels sewn together to form the crown. The stitching of these panels met in one place at the very top, leaving a somewhat rough and uneven finish.
To cover this, manufacturers added a small round piece of fabric-covered metal — the squatchee, which we now simply call the “button.” It wasn’t meant to be decorative at first. It was practical: it kept the panels secure and gave the hat a neat, polished look.
