Try what everyone else has said first, they know what they are talking about. with more practice it will become second nature.
For example I am riding my mower down a stripe and will need to turn left at the end.
Before I reach the end I make the mower turn a bit to the right and then when I turn left make it turn enough to line yourself up with the next stripe, but dont turn so hard the right wheel stops.
By turning a bit right before left when you turn left without stopping the wheel you would still be lined up for the next stripe.
