These are the Golden Nights, the novena leading up until Christmas. At our home we begin the Golden Nights when we begin the O Antiphons. We add golden metal leaves (easy to find at resale shops) to our Advent wreath. I also have a golden cloth I will add. I look for golden things throughout the year while I am at resale shops to add to our decorations at this time of the year. My eventual goal is to have something to add every night that leads from now up until Christmas.
It is just another way to help the children realize how extraordinary the feast of Christmas is, and how much we must do to prepare our hearts for the graces God wants to give us at this special time.
