From the experts at HouseBeautiful.com:

  1. Don't mix up presents -- write out the tags as soon as you wrap the gifts so there's
    not an embarrassing mix up
  2. Don't let the Christmas lights become a safety hazard... watch out for loose bulbs or
    protruding wire.
  3. Don't go overboard... when it comes to Christmas decorations, less is
    more.
  4. Don't expect things to be perfect ... no matter how far you plan ahead, something will
    go wrong.
  5. Don't keep your Christmas lights on all night... they say this one could be bad for
    your relationship with your neighbors
  6. Don't use disposable silverware for holiday dinners
  7. Don't limit yourself to red and green ... hues like gold, pink, and navy blue can
    work, too
  8. Don't think that poinsettias are poisonous... yes, they'll upset your stomach if you
    ingest them in high quantities, but it won't kill you. Still keep them out of
    the range of children or pets (just to be safe)
  9. Don't ignore the powder room ... With company dropping by, make sure your guest
    bathroom is clean. Toilet paper, clean towels, soap...you get the
    drill.
  10. Don't have your Christmas tree up at Valentines Day.
