And here is what we have done in the dining room. The pictures on this wall are all of places we have lived. We have scoured historical society archives, stock photos, and even begged one photo off a family member (thanks, Scott!) in order to get what we wanted from each city. The center frame says, "Home," and underneath that, "is where the heart is." After six states and three countries, we are living proof of that. (And you can see it much better from a different angle - still trying to figure out what to do with that chandelier.)
And for fun, here is what I put up in the mudroom (which you walk through to go from the garage into the kitchen, so nobody will even see it but me). I found these fun vinyl letters through Tip Junkie. I am sure everyone else in the free world already knows about these, but they were quite new and exciting to me.
