Here is my plain candelabra; nice but needs some sparkle.
Remove the bottom plates. You will need to purchase a very thin drill bit that is used for metal Carefully drill holes in. I drilled 4 holes in each plate. I also drilled holes in the arms of the candelabra.
Purchase some crystal beads, or you can even use acrylic beads in any shape you like.
I removed mine from an old chandelier, that had real crystals. Nothing sparkles like the real thing.
Hang the beads, and presto; new looking candelabra with sparkle.
