How to flirt girl to girl
Be friends with her, if you see her regularly.
If possible, before you start any flirting with her, get to know her and become friendly with her. If she's a girl you like at school, begin by talking to her in class and saying hello in the halls.

Options are:
-While some of the other girls you know most will do the same thing, keep your interactions simple, but definitely talk to her. If she's friends with you and there are a lot of interactions going on it could make the balance seem awkward.
-If that goes well, text her, call her, or ask her to hang out. If you don't like her as a friend, then you probably shouldn't be flirting with her.
-Otherwise, talk to her in the office, at the football games or on her birthday, etc. You want a connection and something to talk about.
-If she happens to catch your eye frequently, smile and brush it off. If it's easy or just plain obvious, talk to her regularly.
