The mom of one of my two maids of honor (I have two best friends, couldn't choose one) is a fantastic piano player. My fiance and I are both very close to her. That being said, we want her to be the pianist for our wedding. I'd like it to just be as a wedding gift...but I'm not sure how to say that/how to ask her. Do I even mention that it would be in place of their gift (I feel like that sounds tacky...is it?) or do I just ask her to play or what? I'm not sure how to go about this. Any advice would be appreciated
