If you have a boring entry, or really any room, you can add a ton of character by simply adding a board and batten wall panel detail. It is not expensive, but it is a classic look that adds a lot of charm to a space.
Your situation might differ depending on your existing baseboard and/or casing, but the 2 examples below should help you to create your own paneled wall detail. Here are a couple of before and after pictures.
Give this project a try. You will be amazed at the difference in feel that a board and batten wall detail will provide in a space.
