This is particularly important when pulling up the walls; your hands are either side of the wall of the pot but need to stay opposite each other to bring up the wall evenly. Make sure your hands are touching is some way, even if it's just touching your thumbs together above the rim as your fingers do the work inside the pot. You'll find your hands can 'talk to each other' more easily if they're physically connected.
