Thanks for the reminder Karl.
One thing we have done is send a magnet which went over pretty well. (As in I have seen it on many fridges since then.) We found a really cheap deal for a tiny one (2" x 2") that just has our face and names.
The other thing is that it is definitely worth being consistent in updates or reaching out to people you want to see over the holidays NOW, because other wise you get lost in the mix and in some cases end up having to see the person in person at an awkward party or something before they actually get back to you.
