Christmas is about nostalgia.  Retailers recognize it too and there are lots of color palettes and patterns that hearken (you don’t get to use that word often, but ‘tis the season) to the mid-century era.  I have vintage Christmas ornaments that I mix in with current ones.  I also have old Christmas light boxes that go around a vintage tree.  Vintage for you may be a silver tinsel tree or simply tinsel.  Whatever your nostalgic memory is, bring it into your home this year.
