If you are using a pricey rug in your entry. Do what I do. Protect it with a small washable throw rug. Covering the spot most traveled on a daily basis. Then for special occasions stow the throw rug in the closet. Meanwhile, the better rug will stay clean. No space for a rug? Paint an interesting design on the floor.

When it comes to the amount of lighting, foyer always needs more amount of light as it is the front entrance. Also, see to that you do not provide too much of bright light. That may result in producing glare, right at the entrance, and this may annoy the guests when they step in. But if you have anything really attractive in your foyer or if you have a staircase there, then it is mandatory to use a bright foyer chandelier or spot lights. If you have beautiful pictures or paintings displayed on your walls, you can showcase them with gallery styled accent lights or track lights in your foyers. Accent lighting is always an added advantage for foyer decoration.
