In this tutorial, we learn how to throw an upside down double walled pottery vase. Start off by using water every few seconds to craft your vase. Use your fingers to press down in the middle, to make the round shape and have the vase rise up into the air. Make this into a bowl shape, which will be into the air. Next, shape the middle using your hands into a triangle shape. Raise the side bowl around it, and keep using water to increase the size of the bowl. Collar the bowl in, then start to mark holes throughout the entire piece. When finished, you will be finished and have a beautiful vase!
