The yunomi shape is one I have done for most of my career. The form derives from the Japanese tea ceremony although I am not a practitioner of the tea rituals. The form considerations for the yunomi are that the height is somewhat larger than the width ....making for a more upright configuration than the typical tea bowl shape.
Tumblers are a rather universal drinking shape which I greatly enjoy making whether for individual use or as part of a dinner ware grouping.
If you see pots you wish to purchase, please go to the TO PURCHASE page for convenient directions on how to do so. Thanks !
