One of my relatives has started a new business called Word Diva Designs.
Check out her website. She's selling vinyl designs and/or lettering that can be applied to walls. It looks really nice and the best part is that you can remove it if you decide to redecorate later. It's very affordable, and it's customizable, so if you have a favorite quote from a book, song, or Bible verse, you can let her know what you want (font design, color, quote, etc.) and she will work up a design for you and let you proof it before you buy it.
You can see example pictures in the picasa galleryhere.
There's a place on her site where you can become a "fan" on Facebook. I'm sure she would really appreciate your support!
