Swinging gift tag AS2

Hello there,

I’m creating a series of christmas banners and the main image I will be using across all of them is a gift tag. I would like to add a subtle animation to the gift tag so that it swings / sways (very gently and subtly) for the entire animation (probably around 15 seconds) and then stops in a certain position at the very end of the animation. I’m trying to achieve this using AS2 but don’t really know where to start. Can anyone help please…?!

Thanks in advance!
