vintage doors mounted on barn door hardware. This could be done in place of the french doors we have in our office. It would really save space and make the room more usable (think external pocket doors).
Clean out the attic or find cheap, kitschy things at a thrift store and spray paint them white (or any color you'd like). An easy way to have a crisp, modern collection of items to decorate any room.- let's go to some thrift stores!
