I am getting way ahead of myself... invites aren't done, we have no idea how much it will cost to send them out... but I am looking at postage. My main stamp choice for years has been the Breast Cancer Awareness one. I have also liked the Reptiles & Amphibians, Dr. Suess, Paul Robeson, and the Ecosystem series. However for the invites... I may want to try something new. I checked out the USPS site and found some beauties in the Scientific American Landscapes series. I love the Okeefenokee Swamp and Hagatna Bay stamps, but have enjoyed my time in the Smokies and Yosemite.
