How to make a girl enjoy your company or become friends with a girl who sits next to you?

In one of your classes. She is pretty and popular, but I just wanna be friends with her and get used to talking to girls. I'm small, and it kinda bothers me, but people say I'm good looking. So, without being nervous, how can I make her laugh, and enjoy my company?

Also, I only talked to her once, she picked up a paper for me and I said thanks and she said ur welcome :))
