You MUST roll your clay onto the tile and also use a method to prevent sticking. I prefer to use cornstarch. You can also cover your clay with cling wrap, but this will cause a rounded edge. Press down, wiggle a little, and gently rock back and forth to release. I would also recommend using firmer clay (place in the freezer or refrigerator for a bit if it's soft or sticky).
