I ordered this for use in a vintage 1937 powder room that faces a patio and needs some means of preventing users from being observed while using the toilet without obstructing the minimal light provided by the tiny leaded glass window. This item looks nice and fit perfectly - hung from the top of the window, it allows a little full light around its sides and filtered light through the stained glass of the piece. I think it nicely blocks some of the cold air that normally comes through this window, and the powder room is not too cold.  Additionally, the piece is attractive.
