I would recommend, if your friend is having a Christmas themed wedding, that said friend could buy a tabletop Christmas tree as a centerpiece for their reception tables. They could also buy either snowflake or red-and-white striped place mats, depending on their color scheme. A wonder flower she or he could use would be the poinsettias, as they are popular and beautiful Christmas flowers. Even Christmas wreaths or mistletoe would be a excellent edition to your friend's Christmas-time wedding.
Christmas lights, Christmas tree, wreath, holly, mistletoe, paper snowflakes, etc.
Any decorations that you buy together would be good. Or any decorations that you make together. The main thing in a first Christmas as a married couple is to make it special for you.
