These are the cards I have received in response thus far, and they have all made me so happy! :)

kitty_vayne- You are the first postcard that I can proudly add to my collection. I didn't know a lot about Iowa so I was glad you wrote about that. :) Thank you so much!

Marisska- I really enjoyed the postcard of Spain! Thank you and a happy new year to you as well. :0

Icanmakeyouhappy- Aw, I love your telephone box postcard. The quote is pretty great, and I'm choosing to give your card meaning. Thank you and tell the Queen I also say hello!

FUZxxl- Your postcard was also incredibly cool and I loved even more about what you wrote on it. I really did not expect so many stamps, you are very generous! I really like them and I will add them to my Germany section of my collection. What is it that you wrote on the seal of the envelope? I hope to exchange more cards with you as you wrote in your post.

Thank you all!
