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.
