1. I bought a cheap lampshade at Target, then removed the paper shade. The adhesive left behind proved to be difficult to remove from the top ring. After trying several methods unsuccessfully, I rubbed a cotton ball soaked with lighter fluid on the ring, and the gooey gunk finally came off. Then I washed the ring in soap and water to remove the lighter fluid.
This was such a laborious process that I thought I’d find a supplier of what they call “slip uno top rings” to save us all some trouble. You can buy them, but they’re ugly. Most are half unfinished and half gold-plated. I spent weeks searching online, driving around town, calling and emailing manufacturers for a chrome top ring — without success. So I suggest finding a lampshade with a pretty top ring and rip it apart — or spray paint an ugly one.
Tip #1 If you’re into the work, strip the lampshade’s bottom ring as well and make a mobile out of it.
