Christmas announcement....

...ideas please :) We plan on telling our immediate family on Christmas Day....we will be staying with my husbands family on Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>/Day (my family will be 3 hours away) but we want to tell them both on the same day....so I need ideas on how to tell his family whilst we are there and my family who will unfortunately not be with us on the day (but still want to make it extra special for them as I won't be with them) Thanks :)
