Sometimes...when a show gets slowish...like the last hours of the last day...craftspeople start "talking shop." My insistence of trimming my yarnbowls sometimes comes into the discussion. The other potter's concern for speed is usually the anti-trimming portion of the discussion.
Some would not trim the bottom of the pot, leaving is a flattish sort of bottom. By necessity of the process the edge that meets the table will be visually terminated below the top of the table...sort of like the pot is sitting in the table rather than on the table.
I prefer to give the pot some visual "loft" by trimming a foot into the pot. This gives the pot the appearance of sitting on the table and from a distance, it looks lighter on the table. All my opinions of course, but I think the pot looks more finished.
Jim writes most of the dribble for our Banter. Sometimes it's serious, but often not...then, neither is Jim
