I use my dining room table (covered with protection) and lay every swag and garland and other stuff on it before tackling "the tree"! I wrap and put away all that stuff, and put the normal pictures & accessories back on the walls, tables, piano, fireplace mantle ...
When that's done, THEN I take all the ornaments off the tree, laying them in groups (the way I store them in boxes) on the dining table, and boxing those. Last are the lights (I don't use a pre-lighted tree) and finally the tree itself. We don't always do too much lighting outside, so it's not a big chore to 'undo' either - mostly wreaths on the doors and gates.
Christmas is usually GONE here by the day after. :)
I never do mine the day after....I’m usually too tired! And each day, I promise myself...today I will get’er done. After I do get it done though, it makes me feel great! My tree is pre-lit but I put on so many ornaments, it takes a while to take those off and pack them. I decorate my den and my living room so I have a lot of “stuff”, too! Something on the front porch and the back door entrance ‘that everyone uses’ to enter!
