Not much tradition left to my Christmas since I've married and have a stepchild. We have him every other Christmas Eve thru Christmas day at 2:00 pm. The one thing I've tried to hold true each year is that we start our Christmas as a family (just the 3 of us) and open presents together. Then we go to DH's parents' house for the Christmas meal.
In my childhood, we had many. One tradition that developed when I was a teenager was to buy a 1000 or more piece jigsaw puzzle and work it on the coffee table in the living room at my parents house. Sometimes the puzzle was bigger than the table which was a challenge! Everyone in the family joined in and it was a big deal to see who would place the last piece. Some years it took weeks of Sunday afternoons together to finish. It prolonged the memories of Christmas day.
