I make unique - birthday, baby, anniversary... cards for each individual.
Christmas I make the same. I have always liked sending the same card to all at Christmas. Mixed card boxes used to drive me nuts.
I must get started soon. I normally computer generate a brief update, and internal greeting as well as a back, so I can't do it too early. I probably will do the 2nd design I came up with last year as I am struggling with mojo. Both stamps are at least ten years old so no danger of them being in style or the latest and greatest either! LOL!
