That small hole at the tip of a safety pin is a built-in guide, meant to turn a flimsy piece of metal into a precise threading tool. Slip a piece of string, yarn, or thin cord through the hole and knot it, and the pin transforms into a lead shuttle that pulls elastic, ribbon, or drawstrings through fabric channels with control instead of chaos. The cord keeps the pin aligned, reduces twisting, and makes it much less likely to vanish into a waistband or sleeve.
This is deliberate design, not an accident. Long before plastic bodkins and specialty threaders existed, seamstresses and tailors relied on smart details hidden in ordinary tools. The safety pin’s hole is one of those quiet solutions, passed down without fanfare. Notice it, use it, and a humble, bent piece of metal suddenly feels like a tiny, ingenious machine working in your favor.
