As a knitter I have several scarves. Scarf pins are a great way to help spice up a basic scarf or to tie it up in a unique way. These pieces can really make a statement in your wardrobe and be a great conversation starter.

The other great thing about this is that they can be used as more than just a scarf pin. I've seen them used as hair pins to hold up buns or pony tails. They can also second as a broach too.
