I just found two things I am going to participate in. One is the Holiday Mail for Heroes program through the American Red Cross. I am going to pick up a box of Christmas Cards on my way home and Princess Ivi and I will get signing tonight. (Edited on 12/3/09: Our cards are on the way!)
The other program is Operation Baking GALS (Give a Little Support). This sounds like such a great program. It will allow me to bake which I love and support our troops which I love. Double the pleasure!
