I love sending out Christmas cards. Its what I do to get myself into the holiday spirit. I finally got them all in the mail this morning. I sent out twenty-two this year, and a couple of people even got a letter included in theirs. I usually receive about half as many as I send out, but that's okay, because (like others here) it puts a smile on my face when I receive one and I hope it makes somebody else happy to get one from me.
For the last few years I've put a lot of time into making my own cards to send out; cardstock and stamps and all of that jazz. This year I just didn't have time for all of that so I bought tha prettiest boxed cards I could find, bought some pretty mailing labels and put a little snowman sticker on the back for a seal. Not handmade, but pretty good all the same.
