I like the Halloween porch spotted last week by Sabina of Barefood in the Orchard. I could not find any details on where this picture came from. If you have a talent for designing scenes, it used props that are widely available.
Why not revive the 70s candle in the wine bottles? Finish the vignette with artificial web. You cannot find something easier to do.
Basically, it involves printing a stencil on a brown paper bag. Fill a 1/5 to 1/4 of the bag with sand. Put the typical votive candle inside, make sure the glass cover more that the flame. Martha recommends putting a little water inside the glass before inserting your candle. It is supposed to ease the cleaning of the glass. It is even safer to use battery-operated candles.
