1. Use your own handwriting. Chose a tasteful pen. Write slowly.
2. Write for consolation, encouragement, or to share you life with a close friend. Or write strangers whose work you appreciate. I write musicians, authors, and more They almost never write back. The exception is Peter Brötzmann.
3. Ponder before you write. Pray, too.
4. Perhaps adorn the card with stickers or your own drawings.
5. Although I always want my cards reciprocated in some way, I almost always write more than I am written to--at least since my mother died. If someone never writes back after two or three cards, I usually give up.
6. Be creative in conveying truth and love in this way. It can mean much to many. I know.
