Pins have sharp points, so if you are cautious, you can avoid puncturing your skin. Possibly you intended to ask about pin cushions, not pin caution. A pin cushion is a little pillow into which pins can be stuck, in order to store them conveniently. The reason for using a pin cushion is that it positions the pins for you, with the head outward and the point inward, so they can be more easily grasped.
