I'm a member of Soldier's Angels, too. It's a great organization! I'd like a spot in each category and all of my cards will be donated.
Thanks so much for doing this. I still keep in touch with the soldier I adopted in 2008. She had no one who kept in touch with her while serving in Afghanistan, and was so surprised when my first package arrived (it got there before my first letter) she called security to check it out! Soldier's Angels also supported my son while he was in Iraq. He saw first hand how they helped soldiers who didn't have anyone to support them and was very impressed.
Good luck with your first swap!
