Lets face it. Unless you are Michelangelo, your ceilings are probably bland. Ceilings are among the most undecorated parts of a room.
The floor has (carpet, hardwood, something), furniture, and various objects.
The walls are probably the most festive, having paintings, pictures, and many things.
have ceiling fans and lightbulbs. Which is worth nil in aesthetics.
The problems of decorating a ceiling is that, barring Michelangelo, you really cant do much. Maybe a few posters with unseemly tacks.
You cant do furniture, too heavy. You cant make little alcoves to stick items in, the items obey gravity and fall.
And paintings, the frames arent made to hang from a ceiling.
So design a set of picture/painting frames with special hooks at the corners so you can put eyehooks in the ceiling and make yourself a Mona Lisa Ceiling.
This all comes from my attic entryway, which the entry door was painted to look like the ceiling, leaving what looks exactly like a picture frame.
