Hazel, congratulations on meeting your 2012 challenge!
I think I once had about 6 sympathy cards in my stash and then an extended family member passed and he had 6 siblings remaining, so that wiped me out in one fell swoop. I've never caught back up since. But it is a most excellent goal!
CCC13 is a great challenge to help you with the Christmas cards. It can't make you do the work involved, but I think it does help to motivate you to get at least some done before the last minute. Particularly when you are watching the galleries and seeing the neat stuff everybody else is making. I highly recommend it.
