- At first, wheel throwing seemed hard, but after multiple trials of error, I made a piece that was even and centered. I learned that by clapping the clay once it's on the wheel that it will help center the piece and if the clay gets off centered, you can pull it towards yourself. I also learned to pull the clay up and push it down and when your ready to open it, you push your thumb into the center and pull up or out. And once the piece is finished leave it on the plate until its ready to be taken off.
