Hanging lights on branches. Go natural with a fat branch and hang a combination of ornaments and candles attached with wire. Use twine or strong fishing wire to suspend the branch from above. You might want to try hangers so as not to damage your ceiling.
DIY hanging lamp using mason jars. Hmmm, this has me thinking of that other craft for tinting the glass jars. How about using those smaller rounded "fancy" canning jars and tinting them, and making pendant lights for the kitchen bar?
