What is wrong with it? What type of shade is it? You might want to re-cover it.
Is there a hole? Is it structure issue? We need a bit more details.
Margie....Can you send a picture of the shade? Thanks
CAn you share a photo? You can glue fabric over the existing fabric by wrapping the fabric around the metal and then gluing it right around the metal.
I'm not sure what's going on with your shade, but there's some good info in this video: https://www.youtube.com/watch?v=0GeoqejTJX0
