What a cool idea this is! Outdoor Chandelier: Replace the light bulbs in an old chandelier with inexpensive solar lights & hang it from a tree branch. You'll have gorgeous outdoor lighting without having to hook up electricity.
I don't have a fence, but like this idea. Find old windows, replace the glass with mirrors and put these on your fence (if you can). The mirrored image of your garden on the fence will make your yard look bigger. It's an easy trick!
