How to make friends easily when you're the new girl?

I moved to a new school in March and we just ended school at the end of May. I started out being the really quiet girl and made a couple of friends, but we aren't really close friends who would hang out outside of school or anything. I'm still kind of branded as the new girl and I wanted to know how I could make it easier for me to make friends so everyone doesn't think that I'm weird or antisocial. I was pretty stand-offish these past two months I was at the school because I'm moving again next summer and I don't really like the state or school I'm in right now. I want to make friends now, because I realized how long this school year is actually going to be if I don't decide to try to make any new friends. So what I'm asking is, how can I start over and try to be more open and nice and make friends easily. Another problem is how to make things go by faster. (The people here aren't the nicest, so it's pretty hard to make friends) but I just want to make friends so I don't stay an outcast.
