This is a simple way to make a cover for a glass bottle and turn it into a good looking, practical water bottle. You'll reduce risk of breakage, increase the insulating factor, make it more functional and hopefully improve the aesthetics. It's a great project for those who would like to make their own picnic set or camping gear as well as forgetful folks who are tired of losing $20 water bottles.
Step 1: Materials
Any bottle will work but if you use a Grolsch bottle or something similar you won't need a stopper. That's a great advantage but you can always make a cork stopper or even a carved wooden one and use any bottle you have on hand. For those who don't know, Grolsch is a type of beer that comes in a resealable bottle. It's usually inexpensive and even if you don't drink, it's easy to give away beer. There are lots of other things that come in bottles with wire bales or "swing tops" as well. They've been around for a very long time. The one in the photos came from a widely available non-alcoholic juice beverage.
