This will start to create height and will help even out the walls.
With a little pressure, drag your sponge across the bottom of your piece to remove excess water and flatten out any bumps. To begin pulling, place one hand inside the opening to stabilize the wall. On the outside, use your pointer or middle finger to create an indent at the base of your piece. Applying pressure from just the outside and maintaining stability on the inside, begin slowly relocating your clay up the wall of your piece. This will start to create height and will help even out the walls. Continue the pulling process until you’ve achieved your desired height and wall width. To shape your piece, push the clay out and in. Make sure you are slowing your wheel down as your piece gets taller to prevent a wobble.
