If the pine needles are dropping and the branches are nearly bare, but traditionally you like to have festive decorations around the house for New Year's eve or Twelfth Night, try John van Doorn's approach: before the ornaments are packed away, place a mass of them in a striking glass bowl.
Magnaverde has added to this post a lovely comment about a Twelfth Night party his mother hosted decades ago. The event involved numerous footed compotes filled with collected ornaments. Be sure to read it. You'll want to steal the idea.
