You’ve used safety pins to fix a hem, hold a diaper, or temporarily patch a torn seam. But have you ever stopped to look at that tiny hole near the rounded end — the one that doesn’t seem to do anything?
Spoiler: It’s not just decorative. That little hole has a smart, practical purpose — and once you know it, you’ll never look at a safety pin the same way again.
The Real Purpose of the Tiny Hole
It’s a threading guide — designed to help you attach ribbon, string, lace, or fabric tape quickly and securely.
Here’s how it works:
Thread a piece of ribbon, twine, or elastic through the small hole.
Use the pin to fasten your fabric as usual.
When you pull the pin out later, the string stays in place, marking where you need to sew, tie, or adjust.
Think of it like a temporary anchor — it holds your guide thread so nothing shifts before the final stitch.
