We decided we wanted a barn door to separate our doorless master bathroom, and started researching hardware online. Everything was upwards of hundreds of dollars, and way out of our price range. So my husband got creative and thought, "Why not use a trolley rail?" So we headed down to Lowe's and bought a six foot long trolley rail for about $25, and decided which hanging kit we liked (the hanger with 9 bolts) which cost $30. We built a door out of tongue and groove paneling, stained it blue (my husband has been dying to stain something blue) then later on painted it white (wife wins again!) The entire project (hardware + building our own door) cost $140, which is a fraction of the cost of the fancy hardware!
