Christmas cards

What do you do with the Christmas cards you've received, after the season's over? Recycle them in the paper bin? Save the photo cards? Save the ones with personal messages? Use them creatively somehow? Give them to some organization? (It seems to me I've heard of a place that accepts them, though I can't imagine they wouldn't receive more than they could possibly use.)

When I was growing up, my mom used them to make gift tags, and we would help. It was fun studying a card a trying to figure how best to cut it up to make an interesting tag. But somehow, I just don't see myself doing that these days. At least, I haven't yet.
