birthday where each one had a bow (inside of the envelope). Apparently she took them to the post office and argued with the employee behind the desk for 10 minutes because they couldnt promise that the invitations wouldn't be sent through a machine that might crush or flatten the bow.
But in her case she chilled out a lot with kids 2, 3, and 4. I don't think she sent out invitations for any of the parties for their youngest 2 kids.
