I had to run to Michael's to make this card because I did not have one cross stamp to make a card for my nephew's First Holy Communion. I printed out a sentiment for the inside of the card, and this is what it says:
In honor of your First Holy Communion:
May love surround you,
May faith sustain you,
May hope encourage you
Day by Day.
I found the sentiment in the Blessings section of The Ultimate Guide to the Perfect Card.
