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.
Fall flowers/leaves or berries -----Falls Flowers Wedding at Rutgers Sun & Shade Garden - light bulb flower holders- so freaking cute! Possibly with fall flowers and mason jars or bottles hanging in between the light bulbs
Tea Light Bubbles: Cascading candlelight makes for a luminous and delicate alternative to a traditional chandelier. We love this idea for rehearsal dinners, weddings, and even holiday parties. So pretty! I think id do this at Christmas x
