• Water Carafes: One of our favorite re-uses, hands down, is to keep three chilled bottles in the fridge at any given time, which is not only a treat on a hot day, it's a great way to avoid wasting tap water while you wait for it to achieve the desired temperature.
• Infused Oils: Check out this article for instructions on how to infuse your own oil, which you can store in your lovely, clean bottles. Half bottles are particularly good for this one.
• Kombucha: Another MIY treat, check out this article for the deets on Kombucha with a link on making your own tasty cure-all beverage.
• Soap Dispenser: With or without a bartender's pour spout on the opening, you can make a pretty dish soap dispenser with a clear bottle and colored liquid.
• Flower Vases: Line up several wine bottles, and insert a long stemmed flower in each, such as a gerbera daisy, sunflower or birds of paradise. These are lovely in a window sill. You can also cut the top off straight or at an angle for extreme elegance.
• Tumblers: The next few ideas involve going to a glass cutter, which we realize may stretch beyond your DIY comfort level, but for the uber dedicated, take eight wine bottles to a glass cutter, have them cut at your preferred height and take them home and sand them to remove any scary edges. If you're a real DIY-er, check out this post from Instructables to learn how to cut your own, and always take proper precautions when cutting glass (gloves, goggles, you know the drill.)
• Candle Votives: Same as above, only shorter
• Night Light: Drill a hole in the lower back of the bottle large enough to insert a small string of LED Christmas lights. Slide your lights in, put the cork or cap back on and voila, instant night light.
