Your and FH/H/FW/W's name. I love to see how couples' names flow together. If you have a profile of "STBMrs....", maybe don't. I don't want to make anyone worry about full names being on here.
We are Adam and Vanessa or Vanessa and Adam
ETA: With Christmas coming, I sign the labels or birthday cards differently depending which family they are going to. Your family, your name goes first.
