How to become better friends with someone?

[Catherine]

There's a girl that is in my grade, and we text a ton. We are friends on Facebook, and are following each other on Instagram, twitter, and Pinterest. I have never met her in person, but she is friends with a lot of people that go to my school (she doesn't go to the same school as me). She is super cool, and we'll be going to the same high school, so I really want to hang out with her!

The only thing that worries me is that it will be awkward if we just randomly hung out one day. How can I make this less awkward and become better friends with her? Anything helps!
I am a girl btw! We talk about the guys we like, etc. and we already have a ton in common! I can tell we will be close friends, but I just need to figure out how to become closer friends.
