Fantastic of july idea! Replace center plank of picnic table w/ gutter fill with ice to keep bottles of wine- or any drinks cold. Medlock Ames Winery in Healdsburg, CA: a picnic table as wine tasting bar. Landscape Architects. Photo Dwell. Via remodelista
Fall or winter wedding. Simple yet sophisticated. Can be pulled off reasonably cheap. I like the idea of "bling" in there. would likely use river pebbles as a bottom filler. Would be awesome to submerge lights under the filler to shine UP on the twigs.
