I have had a wooden Advent calendar made in order for the congregation to participate in four weeks of preparation for Christmas (right image). Each row of 5 doors includes figures of Angels, Wise Men, Shepherds, Dwelling Places of God, and Nativity participants that are placed on the nativity platform after readings are read during the Sunday service.
I have also had a smaller 8" x 11" wooden Advent calendar made for private devotion (left image). The images and readings are the same, but can be used in conjunction with family celebrations.
I have included the readings below.
