Overall, these cards are fine, except that one of the designs includes part of a scripture: "Precious in the sight of the Lord..." and includes the reference (Psalm 116:15). The rest of that verse is "is the death of His saints." I had to throw that one away; it doesn't seem appropriate for a birthday card.
I use these card to celebrate birthdays in my Sunday School. As Superintendent, I acknowledge birthdays every Sunday, and everyone gets a card! Everyone looks forward to receiving a card, adults and children on their birthday.
