I Love Pins!
I collect them! Pins come in patterns and designs from virtually everything you can be interested in.
I try to find my favorite fandoms or pins that mean something to me. I usually snag the truly interesting or different ones, often supporting kickstarters to help fund projects.
To me, pins go beyond their collection value, a pin signals to others that you are a part of their community or group, whether it's something as apparent as a rainbow LGBT pin, something more obscure like the sword from She-Ra, or something subtle like a traditional lapel pin.
When I wear a large pin or combine my love of bold patterns with something smaller, I'm usually making a statement.
