I made this faux stained glass window to cover a clear glass window beside our front door. Cut the black from posterboard with an xacto knife (2 mirror images), then selected six different colors of lining material and cut them to fit the squares. Glued one, two, or four layers depending on how opaque I wanted it. Used double stick tape to attach the two frames together & attach to the window frame. Was really pleased with how it turned out!
