Find it, Make it, Love it: DIY Board and Batten-Master Bedroom. This is a great tutorial and would work for adding a picture ledge to an old door or window too. May work in the guest space with a ledge less panel covering the electrical panel.
sooooooo clean looking Interior Details. Herringbone floors & white walls with molding. This is exactly what I want in my future home! White furniture and white walls with subtle detail to keep it from getting boring.
