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.
Designing Clay Tiles: If you want to design the tiles, use a pointed but small object, like a paper clip. Using the sharp end of the clip, etch a design on the surface of the tile. If you want to decorate the tile, use small pebbles or beads. Since the clay is still soft at this stage, these things can be easily pressed upon its surface.
