Wavy Side Down
But wait, isn’t that putting it in upside down? You would think so, but that’s what the wavy part of the bobby pin was designed for — the wavy part of a bobby pin grabs the hair, while the straight part holds it down. This way also looks better if your bobby pins are exposed!
Oh boy, I’ve been wearing bobby pins wrong until a few years ago.
