One easy but powerful way to affect the sense of sight is by adjusting the light. Lowering the lights calms nerves, softens appearances and makes any room look more attractive. Bright lights highlight areas where you want people to gather. Spend a few minutes the night before your event deciding how lighting can work for you. Use dimmers to soften overhead lights or simply change a few light bulbs to lower wattage for the evening.
Large gatherings can be a little brighter since the level of energy goes up with the level of light.
Remember, however, that the goal is to flatter people and create a festive atmosphere. The sound of stimulating conversation is often the main attraction at a party. However, other sounds, such as a crackling fire in the fireplace or meat searing in a hot pan, can also enhance the atmosphere. Music can be a wonderful addition to a party, either as entertainment or for a background effect. When using music as a background for smaller parties, be careful that it doesn't become overwhelming.
