If you are in San Francisco with some free time between 6 and 8 tomorrow evening, why not drop by the SF Center for the Book to help authors Carolee Gilligan Wheeler and Jennie Hinchcliff celebrate the release of their latest book, Good Mail Day: A Primer for Making Eye-Popping Postal Art (Quarry Books). There will be amazing people, delicious treats, and raffle prizes (my favorite part!) Event details are here and here. Hope to see you there!
