I send them. Probably outdated but traditional. Like putting them up on the mantle..... They look pretty... And then counting them to see how many less I got compared to the year before so I can see who I managed to piss off somehow....it's all good!
I hand make them (about 40 every year), add a picture of the kids, write a personal message in the majority and pray for each family, and address them (I so need to get address labels). My cards are made, and pictured but not written out yet. I enjoy thinking about each family member or friend and just having that time to be grateful for what they've added to my life in the past year.
