If you choose wallpaper with lots of pattern, you will have very little need for pictures or artwork. When choosing wallpaper, don’t assume that a small foyer should be papered with an equally small printed design. Some of the prettiest foyers I’ve been in, were small ones, where the paper chosen was large scale and very bold. The effect was wonderful! The entry is the perfect spot for tromp l’oeil. Possibly a mural of a Grecian urn or a large topiary.
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.
