American penmanship is becoming extinct, so I think its so nice to either get or give a handwritten card every now and again.  These little keepsakes are adorable:

1. Congratulations  Flower Card by Artecnica
2. Happy Birthday Flower Card by Artecnica
3. Bravo Cartolina Cards
4. Salatiga Note Cards
5. Bird Letter Press Cards
6. Thank You Seed Cards – instead of throwing the card away, you plant it and watch it grow!  Too cool.
7. Twin Kittens Letterpress Postcard
8. Set of 8 Emergency Cards
