Size 4 pins are 3 inches in length, not 4 inches as you might imagine. The largest type of pins are size 4, generally known as blanket pins. The find the right length for you, check the designation on the box. But all brands and types are not the same, especially if you’re an avid crafter.Ĭertain sizes of safety pins are more suited to certain projects or fabrics. You won’t find too much variety in the way of how safety pins are configured. These tiny helpers are essential for any number of projects in the crafting world, from dressmaking to quilting and beyond. But that clasp also makes the safety pin ideal for holding together skirts, shirts or layers of cloth. In its purest form, a safety pin is a sharp metal pin, bent and coiled back on itself in such a way that the point can be tucked away in a tiny sheath.

The humble safety pin hasn’t had much in the way of design improvements since its invention in the mid-1800s, and it probably doesn’t need any.

If you work with clothing or textiles of any kind, you know there’s one fastener you simply can’t do without.
