International Night
Understand the different cultures in your ward by asking each sister who was born and raised in a different country to do a presentation and show items from their country that may be of interest to others. Examples they could talk about: difference between the USA and their country, show the money, talk about the traditional clothing of that country (and possibly wear it), customs of their country, popular music and dances, foods of their birth country, etc. Ask each participant to bring a pre-prepared food to share with everyone after everyone speaks.
We asked each sister to take only 10 minutes but each took about 20 and it made for a very long night but was still very enjoyable.
