One thing I have found when giving critiques is that when you turn some people's work upside down it is often a more pleasing form. I decided to make these bottles upside down. I threw a bottomless cylindrical form a wee bit narrower on top so that when it is turned upside down it will be the narrower bottom. I have always been more attracted to forms that are narrow at the bottom and grow to a broader shoulder.
I threw the bottoms and have attached them to what is the top of the hollow cylinder. Flip them over and you have a form that need to have a neck thrown and attached.
