Whether or not an empty wine bottle is transparent, it can make a great bottle light! Mark where you want the holes to be with some masking tape, drill, rinse the bottle, then stuff Christmas lights through the holes you drilled. (via Wit and Whistle)
Would be great on a dining room table. Wine bottles spray painted for vases. These look good except for the tops. A better quality wine without a twist top or using a glass cutter to really turn the bottle into a believable looking vase.
