The Christmas Card Debate

DH and I send out Christmas cards. DH approves of the card I create and I send them out. That works well. Then comes the issue of whether or not to send out a letter with them.

Pros of sending out letter:
- Explaining why in the world we're in a landlocked state in the South even when DH is active duty CG
- Recapping highlights of the past year of our lives for those we don't talk to often
- They're fun to write (and hopefully fun to read too)

Cons of sending out letter:
- Other than moving and explaining that, we don't have that much going on...
- They cost money to print
- Risk of sounding braggy at what we've done this year
- "We" already have a blog

What would you do? What do you do? Any advice, people?
