Blue Mug was recently two years ago by The Chatsworth Collection. Blue Mug birth announcements are cute and reasonably priced. In addition to their birth announcements, Blue Mug also has matching Thank You notes. We recommend that parents select their birth announcement well before the due date. After the baby is born, we simply fill-in the particulars – Name, date and time of birth and the baby’s weight – and a Guild member store in your neighborhood will place your Blue Mug baby announcement into production.
