If your foyer lacks architectural interest, secure an oversized decorative wall shelf or bracket on the wall directly facing you as you walk through the door. I like to place them on the wall at least five feet high or higher depending on ceiling height. This is a great place to display an elegant antique vase or urn. In a less formal setting you may want to display a simple pot of trailing ivy to add softness. This is also a great idea because it keeps your floor space free of clutter.
A plant stand made of wood; wicker or iron with a luscious green fern is a gracious look. Why not use the foyer as a tiny art gallery? Designate an entry hall area or wall where you can hang paintings or pictures that are special to you. Hang a group of fine prints all framed the same. The prints will stand out more, if the color of the frames contrast with the wall color.
