I want to do something as a way to formally ask my best friend to be my maid (or is it matron if she's married, I never know...) and my two sisters to be in my wedding. I'm kind of just thinking a card with something written on it about sharing my special day with me but I've come up blank. I also thought about puting like a bookmark or something in it along with it but I've come up blank.

Any ideas??
