Yeah, I can go to Target and buy a set of glasses, but it is pretty cool to be able to use/recycle bottles that in many cases go in the trash.
And of course, you can always take pride in the fact that you made them yourself!
WARNING: There is the possibility of injury from broken glass when performing the steps in this instructable. Proceed at your own risk!
Step 1: Get Your Bottle
You'll also notice that most wine bottles have a big "dimple" on the bottom called the "PUNT". It is OK on a bottle, but not so nice in a drinking glass. Some people like the punt and glasses made from these bottles are often referred to as "punt glasses".
I prefer the flat-bottomed bottles commonly used with certain types of white wines. If you only drink red, try Bordeaux bottles, they are often flat on the bottom.
Beware: the nicer the bottle, the worse the wine usually tastes!
Step 2: Cutting the Bottle (part 1)
Wear gloves and eye protection!
There are many tools and methods you can use to cut a bottle; the cutter I used is all metal and I like it better than some of the plastic-framed models sold at craft shops. However, any jig that allows you to make a consistent scoring line around the bottle should be good enough.
This tool uses the scoring method which "cuts" a line around the bottle. Glass of course has a crystal structure to it and can't really be cut at room temp but rather broken in a controlled manner.
Once you score the line at a predetermined size you then move on to the next step.
