My fiance is Lebanese, so we'll be having pre-wedding parties at both of our houses on the day of the ceremony, zaffe dancers, drummers, and a sword to cut the cake. To honour my Ukrainian heritage, I'm having a korovai bread cake (in addition to a traditional wedding cake) and rushnyk cloth for us to step on after we're pronounced husband and wife. And for both cultures: lots and lots of dancing (and toasting... omg so many toasts).
Curious to know about everyone else's ideas for combining two cultures into a single celebration. And I love to hear about different wedding traditions in general so please share!
