On 4×6 inch index cards have each person in the family (or just the children) write Bible verses. It is easiest to have the lined cards for children. If a child is too young, then let them draw a picture of a person in the Bible or some biblical event. This does not have to be completed in just one day. You can work on it until just a few days before Christmas.
After all of the cards are completed, make copies of the cards on cardstock paper. Cut them into 4×6 inch cards. Bind the cards on top so they can be flipped.
This is a great gift for grandparents, aunts, uncles, Sunday School teachers.
