Rarely does the post office create a stamp that I love, much less promote, but the current "King and Queen of Hearts" LOVE stamp is just perfect. I adore the theme, and the subtle colors look great with many different envelope colors. These are standard first class rate ($.44) stamps, so most likely it is not enough to mail a typical wedding invitation which is 2 ounces (a $.61 stamp). However, if you don't mind giving the post office a $.27 tip, you could put both the king and queen on your invite for a fabulous wedding look! I'm not sure how long they will be printing these, so stock up while you can!
