Okay, so I've been in contact with the Volunteer director at the hospital for the past month or so, and she just sent me an email with this attached. Just a few things that she wants to make sure everyone follows.
GREETING CARD PROCEDURE
• Make sure there are no full names, addresses or phone numbers
• Make sure there is no glitter or glue on card
• Make sure there are no photos enclosed in card
Other than that, everything else is fine, so have fun and make some awesome cards! :)
