Cups

So I've been trying to make cups.  The first thing you learn when attempting to throw is how to make a cylinder shape.  Most anything you make on the wheel starts with a cylinder and is then shaped into another form.  Considering that a cylinder is a basic thing you learn and cups are basically cylinders you would think that they would be easy to create.  I find this not to be true.  Its hard to make something simple, interesting, and usable all at the same time.  The solution I have come to with these cups is to leave a larger concave space at the bottom to fit your hand and then add some interest up top by adding ridges.
