how do you address christmad cards a to in laws

[needtomovesomewherewarmer]

I'm a bit late writing them I know. And usually I get dh to write cards to his family as I never know how to address them. He wants me to write to mum etc but that feels rather strange. What do you do?

Hulababy that's what I would do too!
DH would also do the same.
