If you’ve ever used a safety pin, you’ve probably noticed that tiny little hole near the clasp and wondered—what’s it actually for? It’s one of those everyday mysteries that catches your eye, especially when you’re mid-DIY or sewing project. Surprisingly, that small hole serves a clever, practical purpose—and once you know it, you’ll never look at a safety pin the same way again.
It’s Not Just Decorative—It’s a Threading Game-Changer
That tiny hole at the end of a safety pin is designed to help you thread elastic, string, ribbon, or cord through tight fabric channels like waistbands, hoodie strings, or casings. Simply thread a piece of string or narrow cord through the hole, tie or secure it, and use it as an anchor. This trick gives you better grip and prevents the pin from disappearing into the fabric—a frustrating mistake every sewer or crafter has likely experienced.
Why This Tiny Hole Matters More Than You Think
When threading elastic or ribbon through fabric tunnels, the biggest challenge is keeping the safety pin from shifting, slipping, or turning sideways inside the material. By attaching a guide cord to the hole, you gain full control, can pull it back if needed, and avoid wasting time trying to fish it out. It turns a tedious task into a smooth, efficient process—especially for DIY clothing repairs or custom tailoring.
More Than Just a Fastener—Safety Pins Are Powerful Sewing Tools
While most people associate safety pins with holding fabric together temporarily, seasoned sewists know they serve many more roles. From threading delicate trims to securing pleats, they’re essential in any sewing kit. And now that you know about the built-in hole feature, it opens up even more possibilities for smarter crafting.
Try This Hack the Next Time You Thread Elastic
Next time you’re trying to push elastic through a casing, instead of struggling with just the pin itself, thread a length of yarn, strong thread, or even dental floss through the tiny hole and let it act as a leash. You’ll finish the job faster, with far less frustration—and you’ll wonder why no one told you this sooner.
Final Thoughts: It’s the Smallest Tools That Make the Biggest Difference
In the world of sewing and DIY, it’s often the overlooked details that provide the smartest solutions. That tiny hole in a safety pin is a perfect example—a built-in feature that solves a common problem. It’s a reminder that even the simplest tools are designed with intention, and understanding their full potential can make your projects faster, easier, and more enjoyable.
