Use the knife to cut away the extra bits of clay. You can also cut the clay tiles at angles or along curves. If you aren't sure about creating even curves, use a large, slightly_sharp object like a metal bowl. Press the metal bowl upon the rolled_out clay to get even_sized, circular tiles.
STEP 7: Cleaning and sealing __ Make sure you sponge off the residue on the surface of the tiles before it has the chance to dry. This step will require several passes over a period of an hour or more. It's a critical stage when you're working with tiles that have a porous or variegated surface. Dried grout can prove almost impossible to remove from indentations.
