You’ve probably used a safety pin dozens of times — to fix a hem, hold a diaper in place, temporarily patch a torn seam, or keep fabric together while crafting. It’s one of those tiny tools that seems simple but always comes in handy.
But have you ever looked closely at that tiny hole near the rounded end — the one that seems like it doesn’t do anything? Most people ignore it, thinking it’s just part of the design. The truth? That small hole is a clever, practical feature that can make sewing, crafting, and even everyday fixes faster and more precise. Once you know its purpose, you’ll never look at a safety pin the same way again.

What That Tiny Hole Really Does
That little opening isn’t decorative — it’s a threading guide. It’s designed to hold a piece of ribbon, string, lace, or fabric tape securely while you work, acting as a temporary anchor for your project.
Here’s how it works in practice:
- Thread it: Slide a piece of ribbon, twine, elastic, or thin string through the hole.
- Pin it: Use the safety pin to fasten your fabric as you normally would.
- Anchor it: When you remove the pin, the thread stays in place, marking exactly where you need to sew, tie, or adjust.
Think of it like a mini guide or placeholder — it keeps your materials aligned and prevents shifting before the final stitch.
