As we delivered, I asked her, out of idle curiosity, how she plans to use the ones with "Happy Birthday" on them.
Her response was so original that I took her permission to share it here.
When the child goes to birthday parties, they need a tag to put on the birthday present. She would like to use the card to say "Happy Birthday" on top of the gift, and just write her child's name under that braille.
What a great way to make your present stand out!
