Coffee Mugs

I am always trying out new mug shapes with a few things in mind.  Will it feel good holding it with one hand and with two wrapped around it?  Will the shape allow for the coffee to stay hot longer?  Is it well balanced so that it does not fall over easily?  What glaze am I going to use?  Does the design speak to me?  Sometimes I will start with an idea in mind but it can all change once I start throwing and the clay tells me what it wants to do.  Here is a new mug I was working on the other day.
