I got such a nice greeting card on the first day of this year from my friend, South Korea. This year will be nice!!
We exchange New Year's cards in the beginning of Jan. We usually start to prepare for cards from Dec. At first, many people buy blank New Year's cards in post office. We make cards the way we like. If you're good at drawing, you can do. Cards reflect each person's characteristic.
Then, we drop them into mailbox. Mailmen start to deliver them from Jan 1st. If we mail them until Dec 25th, cards will be sent on Jan 1st. (I always drop my New Year's cards around Dec31st. That means, my friends cannot get my cards on Jan 1st. Well, we celebrate New Year not only on Jan 1st also until 3rd. I hope it's not so problem my friends cannot get cards on exactly New Year's day hehe. )
I hope my friends both in Japan and abroad enjoy my New Year's cards. They're not so special but I wrote down messages, remembering friends' faces.
