Use flags and decor items from many nations to decorate the kitty party venue. For example, hang a Mexican sombrero on the wall and decorate tables with Japanese fan centerpieces. Include images and items from every continent and from many nations. You can use knickknacks such as a small Tower of London figurine or small Eiffel Tower model. Use colorful balloons and streamers to bring color to the kitty party. Transform your main bar into an airline ticket counter and use food picks featuring the country’s flags to serve appetizers and decorate drinks for each location.
