In my house if the kids and husband don't do the cards, then they don't get sent. This last year they were late and some did not get one. I always figure if they don't get a Christmas card, the least I can do is make sure they get a Valentine's card and no less than an Easter one if I don't get them any sooner. By then I can get some made up with my rubber stamps or quilting. One year I missed those Christmas cards so I made little quilted heart cards and mailed those instead. They notice it then because it is not overwhelmed with all the other Christmas stuff.
