According to Lucianna,
My advice is that the lighter the door, the easier and less expensive the installation. I've even used closet by-pass door tracks at times, which are fine for lightweight or odd-ball doors. Better hardware, while more costly, can be left exposed as a decorative element. My hardware is utilitarian, and my doors are super heavy (150 pounds!), so I designed a simple trim detail to hide the works. This is a super space-saving way to install doors and an excellent means to grab some storage space just about anywhere. While I have a soft spot for barn doors, I've done this with new flat panel doors painted in fun designs or colors, and all sorts of odd or interesting doors.
