Hi, I'm pretty much clueless on Korean wedding traditions, although I'm 100% Korean.  I am a huge twinkie, and I even speak to my parents in English b/c my Korean is just mangled and they can't understand me.

I do know that traditionally, Korean people give cash as gifts.  And I know that in traditional American weddings, the newlyweds write thank you cards.

My question is - do most Koreans expect/want a thank you card for their gifts?  I'm not trying to get out of having to write a whole bunch of thank you cards after the wedding, but merely asking b/c I am curious.  I'm not sure if I've ever seen a thank you card in my house from a Korean wedding.

Does anyone know? 

Well, I think in this day and age, it's just probably the polite thing to do even if you don't think they expect a thank you card.  I say better to be safe than sorry and offend anyone.  :)

I just asked my mom (who is 100% Korean) and she says that your reception dinner is your way of saying thank you to your guests for coming and in today's day and age a lot of people don't really send thank you cards, but it is very nice if you do. so i say sending the thank you card will be a nice touch if unexpected and safe if expected :)

ooh very helpful pancy!  thanks to everyone who replied.  i will take all of your advice.
