One family tradition that we have is to go to Greg's parents' home for a tree trimming and decoration party. His parents pick out the tree and then call the family members to see who can come over to decorate.
Last year and this year, I was the "outside girl" with Madelyn (Greg's younger sister). Red Christmas bows go around the front door, four wreaths adorn the window shutters, the mailbox gets a little extra Christmas cloth and the new little tree gentle hangs red and gold balls. (They used to have a big tree in the front yard, but the last hurricane took that out.)
While Madelyn and I worked on the outside, my mother-in-law and father-in-law worked with Greg, Jerry, Bonnie, Greg and Casey to decorate the Christmas tree and put up all the Christmas decorations inside. (Bonnie has the tradition of putting the angel on top - when she was 7 years old she put the angel on top of the tree and fell into the tree... so it's a tradition now, not falling into the tree though :)
After everything was in place, we took a family picture :)
