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. There are a wide variety of stencils that you can use if you do not consider yourself an artist. Be sure to use a sealer topcoat to ensure your painted design holds up to heavy traffic and will clean up easily.
Follow your heart! You can be as adventurous with pattern and color as you desire in this room. You can get away with it in the foyer, because remember you are only in this room for brief periods of time. You’ll want the room to have impact and make a statement. Of course, keeping in mind the spaces your entry foyer may be linked to. This after all, is the space where your guest will get a preview of the rooms to come. The goal is to create a continuous flow, room to room, each space complimenting the other.
