This creates a small, firm knot that holds tightly without being noticeable. It’s fast, discreet, and reliable—exactly what you want for a polished project.
The Hidden Use of the Safety Pin Hole
Finally, let’s solve a mystery most people don’t know about—the tiny coil at the end of a safety pin. At first glance, it looks like just part of the design. But it actually has two important functions.
It acts as a spring. The coil provides the tension that keeps the pin securely closed, so it doesn’t pop open and prick you.
It doubles as a threading tool. You can slip a cord, ribbon, or elastic through that little hole, turning the safety pin into the perfect drawstring threader. Instead of struggling to feed a string through a waistband or hoodie channel, just let the safety pin do the work—it slides through with ease.
This simple detail makes the safety pin far more useful than most of us ever realized.
