How to set up a Christmas Post Office in your Corps!
A large, festively decorated, cardboard "mailbox" for the corps lobby with a large slot in the front for accepting different-sized Christmas cards and a flap in the back for card removal.
Decorate cardboard shoeboxes and fill with alphabetized tabs for sorting cards by last name for mail pick-up at the "P.O. counter" (a festively draped table) in the lobby. Use rubber bands to bundle cards for the same family. (The number of sorting boxes will depend on the size of your corps.)
"Stamps" printed on labels (use Christmas clip-art and/or the name of your corps; don't include the year so leftover stamps can be used next Christmas). Avery 5160 labels at 30 per sheet work well. Sell each sheet for $5 (or so) to benefit World Services/Self-Denial.
