We have 7 trees - one in our living room, one in our family room, one in our kitchen, one in each bedroom, & a small one in our foyer. All have lights, ribbons, & ornaments, except the one in our bedroom which just has lights.
The trees were up & decorated the week before Thanksgiving, & all the other inside Christmas decorations were put out the Saturday after Thanksgiving. (All the fall & Thanksgiving decorations were put away the Friday after Thanksgiving.)
DH & older son finished putting out the outside decorations in our front yard & on the front porch & on the front of the house the week after Thanksgiving.
The only thing that hasn’t been decorated yet is our back deck which, hopefully, will be done by this weekend.
All the Christmas decorations usually come down, depending on the year, sometime between January 2nd & January 6th or in the days right after 1/6. Our daughter’s birthday is 1/5, the 11th day of Christmas, so, some years, the decorations are down before her birthday &, some years, I don’t start taking down the decorations until after 1/6.
