We mail out about 200 photo cards, with a newsletter that Dh has written for 30+ years. We have 5 kids ages 23-33 and 1 DIL. This year there are 4 photos on the card because we weren't in the same place at the same time (because of pandemic).
I've got all the extra cards and letters in a big 3-ring binder and it's fun to look at.
We both come from big families and Dh has many, many close friends he keeps in touch with (some all the back to grade school). Writing comes easily for him (Attorney). Organizing addresses in excel and printing mailing labels comes easily for me (Accountant).
It seems like we are always adding people. Even some of our children's friends and parents are on the list.
It's a bit of work, but fun for us.
