1. Chill drinks in unexpected containers. Holden and Moll use the 39-inch-long soaking tubs pictured below left. When the party's over, the vessels revert to soaking tubs (supplied by hot- and cold-water spigots nearby). You could also use smaller glazed ceramic bowls from the nursery as coolers.
2. Hang portable lighting fixtures. White lights are instant magic, strung overhead or threaded into baskets. Holden and Moll also put floating candles in their pond, lanterns on seat walls, and tiki torches among tropical foliage.
