I agree with the other posters about how to word it. The party sounds super cute by the way! Love the apron idea! I just wanted to add that people who still don't RSVP, you should call before you need to put the apron order in...if they show up and don't get one the kids will be crushed and it won't be their fault, it will have been their parents. Don't punish a child for something in which they have no control.
