Why wait until later to start addressing your Christmas cards? You can do it now while you watch TV or a movie or during other down time. It takes no time to whip through those addresses! Just make sure to update your address list first.
If you include a letter in your Christmas mailings, start thinking about what you want to say, if you want to include a picture, etc. By doing these tasks now, you save stress during the hectic holidays.
I've started sending out Christmas letters via email to those whose email addresses I know. It saves a bunch of time, money and the environment!
