When we bought our house just over two years ago, one of the things that I hated about it was the light fixture hanging in the kitchen eating area. It has a big star on each side, which is fine if you're going for some kind of western theme I suppose, but the darn thing is plastic...it isn't even glass! Talk about cheap. There were also two matching sconces on the living room wall and I wasted no time removing them before the furniture arrived, but for the hanging light I wanted to find just the right one first.
The problem was that it was metal...so it's not like I could just use scissors. After going back and forth to my tools boxes several times I finally found just the right wire cutters and literally gnawed my way through the metal plate around the fixture until I had created a big enough hole to remove the shade from the fixture. Then I just cut the excess metal off the main pole to clean it up.
