The space between the tiles should be uniform. Use spacers if your tiles don't come on mesh sheets. The larger the tile the larger the space should be between them. Some do_it_yourselfers will make the mistake of pushing tiles too close together to reduce grout lines. Without enough surface area, grout won't bond well and can fail prematurely, leaving room for leaks and water damage. It's also very important to let the adhesive cure fully.
Getting Started: Start by choosing a smooth, dry surface to make ceramic tiles. The area should be away from any source of moisture, heat, or sudden movements. Kneading Clay: The basic constituent of all ceramic tiles is clay. You need to knead a handful of polymer clay. This kind of clay is more durable (moisture_tolerant) than other cheaper varieties of clays. Wet the clay with water and start kneading it. Knead the clay until the entire clay_mix seems soft and devoid of any lumps.
