What’s the Purpose of That Tiny Hole in a Safety Pin? (It’s Not Just for Looks!)

You’ve probably used a safety pin to fix a hem, secure a diaper, or hold together a ripped seam. But have you ever noticed the tiny hole near the rounded end and wondered why it’s there?

It’s not decorative — it actually serves a clever purpose.

The Real Function of the Tiny Hole

That small hole acts as a threading guide. It allows you to attach ribbon, string, elastic, or thin fabric strips securely while you work.

Here’s how it helps:

• Thread ribbon, twine, or elastic through the tiny hole.
• Use the safety pin to guide the material through a waistband, hem, or casing.
• When you remove the pin, the string or elastic stays perfectly in place.

It works like a temporary anchor, keeping everything aligned before you sew, tie, or secure it permanently.

Simple design — smart function. Once you know, you’ll never overlook that little hole again.
