Trade your ordinary interior door for a farm-chic sliding barn door with these easy steps. You'll need a set of sliding door hardware as well as a door that's large enough to cover your opening. Use a template to mark the holes for your door hardware, then drill the holes making sure to hold the drill perpendicular to the floor. Next, install the hardware. Locate and mark studs in your wall, then mark the wall to mount the track making sure that it's level and leaving an inch of clearance between the floor and the bottom of the door. Attach the track using spacers, attach door stops at the ends, and hang your new door.
