Next I cover the piece of clay with some dry cleaner plastic and smooth it out. Then I flip the clay slab into the dish I am using as a form. The piece of plastic will be between the clay and the dish. This keeps the clay from sticking to the dish.
Next I use my fingers and flute the edge. While this piece is drying I put some tiles in the center of the form so that the bottom will dry flat. You can see lots of examples of finished platters in earlier posts. I pair these platters with small bowls for dip and sell them together as entertainment sets.
