This is a bit embarrassing, but in a moment of weakness (mental weakness), I decided spray painting my curtain rods this metallic silver was a good idea. It turned out looking cheap. So here is my quick fix and a simple way to update any finials (I had to Google what they were called).
Here's what you'll need.
Simply use the glue and wrap the jute around the finial until you've covered the whole thing. If yours are rounded like mine, be sure to cover the whole finial in glue so the jute doesn't slip.
