A manger for Christmas is a traditional Nativity scene, which represents the birth of Jesus. To make a manger for Christmas, you will need a few simple materials. First, you will need a small box or container to serve as the manger. Next, you will need some hay or straw to place inside the manger, to create a soft bed for the baby Jesus. Finally, you will need figurines of Mary, Joseph, and the baby Jesus, which you can purchase at a craft store.
