Wire Lampshade Tap into your inner industrial chic. Cut a wire lampshade frame in half and crimp aluminum radiator grille around the frame. Line the grille with opaque art paper to diffuse the light. Use a light kit to wire the light, cut off the plug, and hard-wire the sconce to the wall. DIY Tip: Use a high-power, low-wattage LED light for long-lasting luminosity and to prevent the paper from getting too hot.
DIY Oversized Patio Lanterns. Wrap a vase with aluminum radiator cover panel. Secure with nuts & bolts. The example isn't cheap, (radiator covers, $38.00 at Rona; Bladet vases, Ikea, $30) but I'm sure you could find less expensive options to recreate the look.
