OOh I just found this thread and got excited as we are having a multicultural wedding too!
I'm from Afghanistan and my fiance is half Aussie/half Macadonian...the families have gotten along really well so far!
and my family have been very supportive even though it's kinda going against the norm for an afghan girl to be marrying outside their culture
the only issue which has come up so far is our mums being nervous about whether there is enough of their own cultural influences on the day (can't be too aussie/too Macadonian/ or too afghan) lol...
But I think we've managed to balance it out
Lovely to read everyone elses posts too
