I wonder about using floating candles in a variety of ways. With flowers in the water? Greenery in the water? Lemons or limes in the water? or even these twigs, water, vases, floating candles. Simple and might be pretty. also, less wax mess to clean up!
Buy 3 different sized clear cylinder vases, a bag of white/tan rocks (or just pick some up outside), 3 fern leaves, 3 flat round candles in either a light green or tan color, lastly fill with water! All these items can either be bought at Michaels
