Will a girl stroke/rub her own legs to flirt?

I was talking to this girl a couple days ago and we hit it off well, lightly teasing each other and laughing together and all that.

Well today I saw her and sat near her and I noticed that she wasn't directly looking at me but she started to lightly stroke her thigh and legs for a bit and then she started talking to me and she was still rubbing her legs.

Was she itchy or cold or something and I'm looking too much into this or was she trying to get my attention
