I have been a lurker of these postcards for awhile now and I just love them all.
Cookie- your themes sound so great. I just wanted to throw in some more for you. Lol. How about picking a US state and doing a postcard on any information about that such as; the capital, bird, flower and other facts. How about themes of movies, eras, inventions, different flowers, circus, a different word each month and we have to create a poastcard interrupting that word such as; create, love, inspire, home, freedom and so on.
Just some ideas
