I've been looking around for (And hinting to my wife that I want) one of those pins with a Scottish flag and an American flag.
Moving over there, I thought it might be nice to get one that has some show that I love Scotland and am proud to be Scottish, but I also love my wife and her country, too.
Figured I could get one, take off the butterfly back and replace it with something more kilt-friendly.

Now, I found a few I liked, but I came across a few interesting pins for various tastes and patriotisms, too.
