if you don't have a fireplace, why not make one? build a frame outwards around 8 inches or whatever and then put candles inside, i think this looks nice! plus, then you have a mantle to decorate for all seasons!
Lantern Pumpkin: Make a natural luminaria by carving long triangles into a pumpkin. A candle or LED light resting inside the pumpkin gives the look of a Chinese lantern. Rest the pumpkin in a ceramic garden urn decorated with fall leaves and berry vines.
