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.
