re: What do you write in your Christmas cards you send out?

Picture card that says Merry christmas on the front.

Some years I put extra cute pics of my kid on the back, and this year we did choose to do that in addition to include a one sentence caption that communicated the gender of the baby And that we are moving and not to send stuff to our old house. Cut and dry.

Minted.com has great options for such an endeavor.
