Help! Late thank you's

We just celebrated our one year anniversary and we are officially "those people" who have procrastinated and made excuses and still haven't sent out thank you's. We feel guilty and have been discussing what to do about it. We've come up with 3 options and need some help deciding which way to go. 1) We just don't do them. Neither one of us is 100% comfortable with this option. My sister pointed out that it's drawing attention to the fact that we haven't done it yet. And that some people may not have even noticed. 2) Send them out now and get over the embarrassment. We'd write a note letting people know that we feel terrible, but have been caught up in our first year and are so very grateful for their gifts and presence on our big day. 3) Sending out a postcard with pictures from our first year with a line like "one year down, a lifetime to go" and writing a short thank you on the other side. Basically pretending like this was our plan all along. Any advice is appreciated. Thanks!
