Combining Cultural Traditions

So with the planning underway, I'm starting a list of various traditions and aspects from each country that we want to integrate into the wedding, and other ways we will emphasize the multicultural and multi-language nature of our partnership and celebration. I will be adding and subtracting to/from this list as I go.

American:
-Bridesmaids and Groomsmen including "matching" clothing (no matching dresses for me, but I like the idea of a color theme, with matching boutonnieres for the men)
-Procession including family members
-Groom comes in first, bride is brought in last by father
-Save the date cards
-Bridal Shower
-Wedding Registries

Bavarian/German:
-Friends plan various games/surprises for the party
-Midnight snacks, party that goes till the wee hours
-Polterabend, where friends bring old china to throw on the ground and the soon to be pair has to sweep it up
-Live Bavarian band (who can also rock to the oldies)

Polish
-Hopefully some pre-wedding celebration food: Pierogies and "Pasteciki" by boy's mom.

Language:
-Ceremony in at least partially German and English, perhaps with a Polish program
-Invitations for each language
-Website in three languages

Other things:
I really liked this photo (see above) of a Swedish wedding with the flags of the couple hanging on a string – perhaps there will be flags at our ceremony, too.
Table seating will be hard, we are hoping to be able to mix it up a bit. Maybe we should have people indicate their language abilities on their RSVP, hehe!
