For this game, you will need several rolls of toilet paper.
Divide your guests up into several teams of no more than 4 people per team. Each team elects one member to be the “mom-to-be.” The other members must design a fashionable maternity outfit for their mom-to-be using only toilet paper. At the end, the real mom-to-be will judge which team did the best maternity clothes design.
A good prize for this might be to give a gift certificate to a clothing store to the “mom-to-be” from the winning team – for being such a good sport!
