Apply water to the mouth, cover the work, press to adhere, and carve out the foot. The holes in the body of the shitta are for carving inside the foot. Tapping it will produce a "pon pon" sound, indicating the thickness. Newly created at the request of graduates of the Hatori Pottery School. I tried setting it on the potter's wheel, and there was no wobble.
