Handle with care. Each piece is made by hand from glass and is fragile. Never display your glass from a suction cup hook. Stained glass is heavy and suction cups pull away over time. Even well-made pieces likely won't survive a fall.
Save yourself the heartache and skip the suction cup hanger.
I recommend installing screws above the window or hardware that is already on your window, like locks, hinges, etc.
Stained glass is made with metal that has small amounts of lead. Handle lightly with care. Wash hands with soap and water after extended handling.
