What are some shy girl signs of attraction?

Anonymous
There is a girl at my church that I like a lot. With everyone else at church she seems really comfortable and talks to guys or girls with no problems at all. she's been going to this church since birth so she knows everyone really well and she's known who I am for like 3 years.

Shes always staring at me from a distance. I always have to be the one to say hi first to her. when I walk up to her at church she always freezes up and looks down and away from me. Seems like she's afraid to even say hi, make eye contact or talk to me. This past Sunday I walked up to her and her friend and she once again froze up and looked down and away so I just said Happy Easter and walked away but as I walked away I'm like 99.99% sure that she quietly told her friend "hes so fine". whatcha shy girls think? What signs of attraction should I look out for? How should I go about getting to know her better? I like her =)
